Heather Block Solutions for QFP SOP and multi-lead package bonding capillaries

SPT’s Heater Block Assembly offers yet another value-added product to further support end-users for their complex bonding application. SPT is capable to fabricate a wide variety of heater block assembly for all types of packages used on any type of wire bonder.

HB SOLUTION FOR QFP SOP MULTI-LEAD PACKAGE

SPT’s “butterfly’ design has proven to eliminate the bouncing effect on the lead finger. The “butterfly” design has shown excellent gripping & clamping stability on lead fingers, especially for high pin counts QFP packages. With SPT’s “butterfly” design, no high temperature tape is required. This has been tested and proven at many customer production sites with superior performance as compared to conventional design.

Advantages:

Absolute lead finger stability during bonding with the “butterfly” design heater block assembly.
The “butterfly” heater block assembly can be applied to a wide range of lead frame design for all types of wire bonder.
Especially useful for FP and UFP high pin count devices.

HB SOLUTION FOR QFN AND POWER QFN

The emergence of thinner form factor requirement, the QFN package has primarily become a popular choice because of its size and electrical performance. However, there is a draw back in wire bonding process using QFN lead frames. The polyimide tape adhered underneath the QFN lead fingers introduce a certain level of difficulty in stitch bonding.

SPT’s specially pipelined designed heater block provides maximum vacuum suction while accommodating a larger QFN panel per index- in order to achieve a stable support during stitch bond formation with minimal bouncing effect.

HB SOLUTION FOR COPPER WIRE BONDING

SPT provides innovative solution for copper wire bonding using heater block design with multi-holes and window clamp- arranged in such a way providing optimum supply of nitrogen forming gas to prevent package oxidation.
