SMALLEST MINI-SYSTEMS RESISTOR MSTF-1 SERIES (11.01.06)
CURE TUNNEL
(10.01.06)
Tremendous 3D, High Speed Curing Power
CON-TROL-CURE’S Cure Tunnel™ is a 4-lamp, 400W/in 3D curing system. The innovative 360° curing zone provides exceptional curing capabilities while maintaining the competitive pricing that CON-TROL-CURE is known for. Utilizing its patented housing geometry, the Cure Tunnel™ is perfectly designed for high-speed,
3-D curing.

Power and Performance
The 4 asymmetrically mounted lamps in the Cure Tunnel™ provide curing power to the substrate utilizing a unique and efficient layout. Each of the 400W/in lamp units is fixed at a 45° angle. This exclusive configuration, combined with the patented housing, enables this unit to outperform systems retailing at nearly 2-1/2 times the price! An exceptional cure is achieved by the 4-400W/in lamps of the Cure Tunnel™, while comparable systems require a configuration of 6-600W/in lamps. The Cure Tunnel™ even has power to spare. A current customer has exhibited satisfactory cure while running their system at only half-power (200W/in).
Cooler Running
The dual lamp layout allows for greater air circulation, keeping the substrate significantly cooler than traditional lamp configurations. Recent performance tests verified that under normal operating conditions, these lamps impart minimal heat onto the substrate. A galvanized steel pipe curing at 350 ft/min left the Cure Tunnel™ with an exit temperature of 76°F. Such a dramatic reduction in temperature over comparable systems means heat sensitive substrates can be cured using the Cure Tunnel™.
CF1000 LED CURING SYSTEM
(10.01.06)
|
The new, state-of-the-art CF1000 UV Curing System delivers the benefits of LED technology in a unique and convenient turn key system. This versatile machine is available in 3 different wavelengths (365nm, 395nm, 455nm) to meet almost any UV activated curing process. Despite its compact size, the CF1000 offers industrial strength curing with a large illumination area for high process throughput. The multi-head capability increases output power and provides multiple angles of illumination (up to three different LED Heads can be powered simultaneously). Independent channels allow only one controller to power the different LED heads/wavelengths simultaneously. |
Not limited by costly battery power or inconvenient charging, the robust thermal management system is suitable for continuous usage. An intuitive control panel makes the unit very easy-to-use and a footswitch control frees up both hands for work. A long LED cable allows for remote positioning and accepts domestic or international AC power. The “future-proof” controller has been designed to guarantee compatibility with LED technology as it advances toward new wavelengths and higher power levels.

NEW UV EB INTENSITY LABELS (13.09.05)
This photochromic intensity indicator is a reliable, low cost, simple, in-house method of monitoring UV intensity. When exposed to UV, the yellow labels undergo a gradual color change from yellow to blue that is directly related to the energy value received.
Made from the same exclusive material as the UV FastCheck Strips, the New UV Intensity Labels (N010-005) have the same color changing principle as the Strips, but they have only 1 color changing square. The New UV Intensity Labels have a sensitivity range that is 5 times greater than the product they have replaced, the old UV Intensity Labels (N010-001).
The dramatic improvements over the old Intensity Labels include:
• Much greater color shift
• More stable, repeatable and consistent color change
• Not subject to increasing color changes at elevated temperatures
The adhesive backed label is placed on a sample product or substrate and processed to proper cure rate. The color deviation can easily be measured with a densitometer or by comparing the colors to test labels created to known operating standards to determine lamp failure or processing inconsistency.
If used on a regular basis, they can detect equipment problems at an early enough stage to prevent lengthy shutdowns. Daily tests can easily indicate a step by step calibration for an accurate reference within each batch. The use of a Digital Tachometer can help insure repeatable results.
Suggested Use: the New Intensity Labels are especially useful in systems where other instruments are not practical, such as 3-D curing, web coating, container printing, medical sterilization, etc.
FEATURES:
• New UV Intensity Labels measure the entire UV spectrum
• Accurate visual determination of UV dose made possible
• Monitor UV dose in difficult-to-access curing environments
• Detect UV lamp degradation and equipment failures
• Provide the user with periodic assurance that their UV source is performing to expectations
• Greater rate of color change provides clearer, more precise UV dose determination
• Determine the dose profile in the 3D curing chambers or across wide webs to ensure even cure
• Measure the dose of sunlight in outdoor curing applications
• Evaluate and compare multiple UV light sources
SPECIFICATIONS:
• New UV Intensity Labels are available in packages of 990 labels (9 sheets of 110 labels per sheet.)
• New UV Intensity Labels Dimensions: ¾"H x 1"W (19mm x 25mm).
NEW UV FASTCHECK STRIPS (13.09.05)
UV FastCheck™ Strips are simple, reliable, and easy to use indicators of accumulated UV light dosage. They are the first product that can be used to determine levels of UV dose with a simple, visual inspection due to the 5 separate color changing zones. Each of the 5 zones begin to change color after a specific amount of UV dose has been received. First the "1" zone begins turning from yellow to blue. Then each subsequent color zone starts to change colors when its specific chemistry has received the proper amount of UV to activate its color change.
The versatility of this unique UV measurement tool allows users to measure a significant range of UV doses. FastCheck Strips measure UV doses from 0mJ/cm² to greater than 5,000mJ(5J)/cm². As well, due to their paper-thin profile and thermal stability, they can be used in all applications where a radiometer is not possible, including: Web printing, Sheet Fed printing, Exposure Verification of exposed products, 3-D curing, and personal UV exposure level testing.
The FastCheck Strips' clearly identifiable color change enables users to visually differentiate the dose differences. UV FastCheck Strips can be further coupled with a handheld colorimeter to measure the dose even more precisely.
As well, we have prepared a comparative dose chart for the FastCheck Strips (N010-003) so that each tested FastCheck Strip can be correlated to the millijoules of UV energy that each color pattern represents. NOTE: This chart is comprised of actual exposed FastCheck Strips.
Made from the same exclusive material, the New UV Intensity Labels (N010-005) have the same color changing principle as the Strips, but they have only 1 color changing square. Click here for more information.
FEATURES:
• FastCheck Strips measure the entire UV spectrum
• Accurate visual determination of UV dose made possible
• Monitor UV dose in difficult-to-access curing environments

TFC9000 THIN FILM CALORIMETER - QUALIFY YOUR INKS, COATINGS & ADHESIVES (13.09.05)
Is it the Inks or is it the Lamps? Know for Sure with the Thin Film Calorimeter.
You need a radiometer to ensure the performance and curing effectiveness of your UV lamps. So, how do you ensure the same of your inks, coatings and adhesives? Up until now, it was mostly guesswork. If you had curing problems and had ruled out your UV lamps as the culprit, your next target was most likely your chemistry. CON-TROL-CURE’s Thin Film Calorimeter (TFC) allows you to quantitatively measure the curability of your inks, coatings and adhesives.
The TFC-9000™ qualifies your inks, coatings and adhesives curability and ensures that they are curing consistently, batch-to-batch. Now you can test the shelf life of stored inks and evaluate older inks to know conclusively if they still perform to your expectations. Less wasted material translates into greater savings and profits.
The TFC-9000 measures the exothermic heat reaction from a polymerizing sample through a highly sensitive sensor. It performs a rapid analysis of the incoming data to produce meaningful results. Once the green "start" button is selected, the curing and evaluation process commences:
• Temperature recording starts
• The UV LED lamp automatically turns on
• The sample is cured
• Peak temperature reaction from the cured sample is reached and displayed
• Once the temperature reaches 75% of the peak, the lamp automatically shuts off
Upon successful test completion, the TFC-9000 displays key measured test results as indicated in the LCD displays:
• Heat Flux
• Peak Value of Heat (in BTU’s)
• Total Test Time
• Slope of the Curve for "Time to Peak" vs. "Heat Generated"
• Current Temperature
• Total Heat (in BTU’s/Hour)
The TFC-9000 works as a stand-alone measurement system or can be connected to a computer through a serial port. The captured data can be exported and plotted to an Excel graph for quick and easy analysis.
Surprisingly, there is no analytical tool which can quantitatively characterize the photopolymerization rates of pigmented UV inks. Pigmented UV curable coatings typically have reduced photopolymerization rates because the pigments absorb and scatter incident UV radiation. As a consequence, the photoinitiator efficiency is decreased and application thickness is limited to thin-films. In addition, commercial UV curable inks consist of pigment dispersed in reactive oligomers. The resultant concentration of reactive groups is low and consequently small quantities of heat are released upon polymerization making characterization difficult.
Evaluating curing characteristics by using calorimetry is advantageous because measurements are not affected by crosslinking reactions and they offer direct measurement of the polymerization rate. A unique benefit of the TFC-9000™ is the ability to accurately measure a very small stimulus. This sensitivity, unavailable in much more expensive evaluation instruments, makes possible the quantitative analysis of photopolymerizable systems which evolve a small amount of heat. Direct implications of this phenomenon include characterization of films on the nano/micro size scale and thin pigmented UV curable ink formulations.
This instrument’s precision and high sensitivity allow it to record exotherm reactions on films as thin as 2 micrometers. With a high heat tolerance, the TFC-9000™ is ideal for heated sample testing. The sensor has an upper temperature limit of 400°F (205°C.)
Note: The system is sold complete with the UV LED lamp. If a different UV source is required, various UV lamp options are available for use with the TFC-9000 system.

NEW P.I. CAPILLARY FROM SPT (13.09.05)The advancement in bonding technology and the market demand for faster, smaller and better product, again poses new challenges for the wire bonding process. The transition from fine-pitch (FP) to ultra fine-pitch (UFP) volume production, and the emergence of stacked die, multi-tier and low-K bonding has increased the level of difficulties in the wire bonding process with more yield loss due to lifted ball, wire shorts, etc.
In compliance with these new bonding requirements, SPT has embarked on an extensive study to develop a new generation and high-performance capillary. Designed with advanced process diagnostic tools, the new capillary design, known as the PI (Programmed Intelligence) capillary has been extensively tested in a variety of wire bonders and packages. In all tests, the PI capillary has demonstrated superior bonding performance with good repeatability and portability using a wide range of bonding platform.
Programmed Intelligence P.I. Capillary
The PI capillary was derived from a series of physical modeling and finite element analysis (FEA) studies to analyze the stress level at the tip and transition profile for different designs, as these are locations where breakage is most likely to occurs. An example of the analysis – in this case, for the PI design is as shown below. Among the options considered, the PI design showed the lowest overall stress. This result was validated through destructive test, which showed that the breaking load for the PI design is 7% higher as compared to other design option.

Laser interferometry technique is also used to determine the optimum capillary profile through amplitude of vibration measurement along the overall profile of the capillary. In wire bonding, the vibration characteristics of the capillary is an important factor as its indicates the efficiency of the transfer of the ultrasonic energy from the bonding tool to the bond pad interface. Through the various design optimization, the PI design has shown to be more responsive to the bonding parameters, producing better bond integrity.

Figure 2: Laser interferometry test results
Based on the various simulation and diagnosis, the PI capillary design was conceived. Actual bonding responses were tested using standard QFP and BGA package for a 70um bond pad pitch (BPP). The PI capillary was shown to be more responsive to the bonding parameter producing better results on all the measures (ball size, ball shear and stitch pull). In contrast, other design options would require higher bond force and more ultrasonic power to achieve the same bond integrity. This observation correlated with the result from the laser interferometry test.

Today, the PI capillary has been qualified and used in volume production by major assembly houses for a broad range of bonding applications. Depending on the specific bonding application, the PI design can be used together with the any existing design feature, such as the DFX (for small ball large wire bonding), CSP (for short loop/low wire bonding, BSB (ball stitch on ball bonding), Infinity (extended tool life), etc. Indeed, the PI capillary has proved to be a new revolution in bonding solution.
CONSTANT AIR BLEED OPTION NOW AVAILABLE ON
ALL COMCO MICRO-ABRASIVE BLASTERS (13.09.05)Consistent operation of the MicroBlaster requires very clean, dry compressed air. This can be easily achieved with the proper dryer installed on the air line. A more difficult task is controlling
the environment where the blasting occurs. Often it can be very wet and dirty, as in the case of hypodermic needle production facilities. To keep the contamination from clogging the nozzles we have developed a Constant Air Bleed Option.
The constant air option functions alternately with the pinch valve. When the machine is turned on clean air immediately begins flowing to the nozzle. As soon as the abrasive stream is activated the bleed turns off. The constant flow of air out to the nozzle keeps contamination from plugging into the nozzle and restricting the abrasive flow.
For more information about the Constant Air Bleed Option, call us today.
