FAQ

Semiconductor Equipment Corporation´s Model 850 is a versatile, semi-automatic placement system for flip chips, chip scale devices and bare die. The system is intended for low volume production and development projects requiring accuracies of +/- 12 microns. A typical application consists of a cycle in which devices are picked up from a waffle pack, dipped into flux and then placed on a substrate.

An optional heated stage (Model 855) is available. An additional option, SEC´s Model 430 Hot Gas Jet Module can be integrated to operate on the Model 850 as a spot heating source for airflow.

Description of Model 850

Color Video System

A motorized zoom lens allows the operator to optimize viewing with its standard range of 10x to 100x. Other ranges are available.

Fiber Optic Illuminators

The system has two separate fiber optic ring light illuminators with separate controls for each, one illuminating the die and the other illuminating the substrate.

Micrometer Adjusted Stage

A micrometer stage is used to adjust X, Y, and Theta to move the substrate into exact alignment with the die. A 4 " square vacuum chuck is provided.

Sliding Table with Brakes

The system has a sliding table which has a 5 " x 13 " travel. Table movement is controlled by a joystick. Pneumatic brakes lock the table in position.

SEC Model 430 Hot Gas Spot Heater (optional)

The Model 430 Hot Gas Jet Module uses heated gas to heat a single die to reflow. Its closed loop temperature control and gas flow control are integrated with the operation of the Model 850. This unit may be purchased as a field upgrade.

SEC Model 855 Heated Stage (optional)

The heated stage is capable of 250 º C operation. It incorporates a separate control box with its own closed loop temperature controls. This unit may be purchased as a field upgrade.

Fluxing Station (optional)

The system includes a fluxing tray to dip the die into flux or adhesive prior to placement. The fluxing station can be added as a field upgrade.
