Application Examples
The solder preforms are used in a variety of applications such as:
Die attach of semiconductor, LED and laser chips, thermal fuses, sealing, thermal interface, connectors and cables, vacuum and hermetic seals and gaskets, PCB assembly, mechanical attachment, package/lid sealing.
Feature
Solder preforms are used in conjunction with solder paste to precisely increase the amount of solder.
Solder preforms gaskets eliminate the need for secondary soldering processes.
SMT solder preforms with carrier tape packaging, simple operation and improved economic efficiency
