If you have concerns, you can look at the datasheet for each component or contact one of their application or materials engineers and find out what the components are rated for...process-wise. IE, how long can I be in the oven with this part, at what

When you look at the capabilities of Combo machines they tend to sacrifice performance when compared to separate X-ray and AOI machines, meaning they don't do either the X-ray or AOI operations as well as a machine that was designed to do only one. A

Maybe this piece of information will help. In China (just returned from visit) there are many factories that are using a dual temperature process using SAC305 or Sn100C and 42/58. Apparently this allows them to run their through hole parts through re

Sr. Tech, you are right in that there is no verification of the profile. We are a Class 3 high mix OEM. We have visual inspection after SMT. We have not seen problems with wetting, grainy solder, cold solder, charred boards, etc. that would indicate

Netters, When I reflow a PCB there is a discoloration of silkscreen and mask. It appears if Profile is too hot! But I dont think so, maybe I'm wrong? 1. Kester 293 no clean 2. 2.1 C/s for 30s to 150 C 3. .5 - .7 C/s for 60s to 185 C 4. 1.5 C/s u
