Attaching Thermocouples for Solder Reflow Board Profiling Using High Temperature Solder
Application Note #00001 Rev: 98-05 Overview This Applications Note covers the attachment of thermocouple (TC) wires to a PCB for part profiling using high temperature solder. We recommend 10-88-2 solder for TC attachment because it does not start melting until…
Minimizing Reflow Temperature Differentials (DT) on Electronic Assemblies Using the KIC Navigator
Application Note #20001 Rev: 2008-02 Background The implementation of lead-free electronic assembly has raised several critical issues for electronics assemblers. One of the most critical is that the lead-free reflow process has a much tighter process window than the traditional…
Developing Common Reflow Oven Recipes for Mixed Production Lines Using the KIC Navigator
Application Note #20002 Rev: 2008-02 Background For electronics assemblers running high mix-low volume production, maximizing throughput can be critical. Changing over the screen printer and the pick and place rarely takes more than ten minutes. For changeover at the reflow…

Wafer Bumping for Flip Chip Attach
There are five commonly used methods of wafer bumping for flip chip attach, three of which are challenging and expensive: Stud bumps formed by ball bonding using gold wire; plated gold bumps using electrolytic or electroless gold; and plating solder…
Production Migration: Do the Numbers Add Up?
PREVIEW By improving productivity and quality, North American electronics assemblers can better compete with China.Here’s how. The continuing economic downturn has shaken the North American electronics assembly industry, leaving in its wake massive plant closings and layoffs. Many…
The Case for Upgrading the Reflow Process
Automating and using readily available and affordable solutions can yield significant gains in quality and productivity. For the majority of assemblers, the solder reflow process has been free of innovation since the use of forced-air convection ovens more than 10…
