Contributors in order of importance: 1. PCB design - if you have large thermal pads, a grid of via holes should be created. Components with low profile will not let the gas to escape from the joint. The only way is going down. 2. Reduce paste volum

There are quite a few papers out there on the subject. Just enter "SMT void reduction" into google or other search engine and take your pick. That said, slow ramp rates and paste volume reduction are a good place to start. Although I haven't tried i

Hopefully you have a dispenser on your machine so that you can add a few large dots of paste to the thermal pad.

Hi everybody, I did post in the past last year and I always got good answers. If I'm going to solder something with Tin-Lead solder and then put it outside (it will be exposed to water, sun, cold nights,...), how long does it take starting to rust?

We've used glass (pyrex, corningware) bread pans in the past, not filling them much over 1" deep. It takes a while but leaves solder ingots sized well to drop back in. Have not tried lead free yet, the higher temp could be an issue using same ty

Hey Gyver: If you don�t mind (which you don�t have any choice about, because I�m going to do it anyhow, cause it�s MY word processor), I�m going to respond genericly, but still be directed to your question. Much of the following is paraphrased from

Questions are: * Is the stencil design proper to provide the correct amount of solder paste? * Is the stencil design proper to provide for release of solder paste? * Is solder paste filling the stencil aperatures, prior to separation? * Are stencil a

Hi, Actually, we want to run a benchtest for solder paste to verify if the paste we use is one of the best. So, with your experiments and tests, what's the top 5 for No-clean solder paste? * I mean leaded solder paste ( for the moment) :)

Can a ROHS PCB with ROHS solder paste can be cleaned in same basin/sink when Non-ROHS solder paste PCB are cleaned? Any detail procedure or cleaning technics for NON ROHS Solder Paste PCB VS ROHS Solder based PCB?

What are the industry standards for eutectic solder-paste in conjunction with the life span of solder-paste. What is the recommended duration of solder-paste on a printed circuit board. Example: You print a board, how long can it sit before runnin
