Hi VChauhan, I'll preface this by saying I am no DaveF. Voiding can occur when the flux in the paste boils and vapourises, the expanding vapour needing somewhere to go displaces the paste. So... what we have done in the past: 1) Step the stencil d

We have some fairly standard 0.1" pitch, two row, shrouded, through hole headers soldered onto a thick backplane. There are tiny inspection holes along the bottom edge of the plastic body that allow an inspector to observe the top of the through hole

Hi Davef, Thanks for your quick reply , just my inputs - we using 99.99 % pure nickel strip for soldeirng & when we do manual soldering this nickle stips its working well but when coming to SMT reflow even after high peak temperature ,its removes ev

We have one, but seem like we hardly use it that much though. I would say it's useful, but not exactly must to have. Most of the models out there would not come with the marking vision system, but you can add it as option. The tricky part of using

Hi, Here we take profile for every changeover. And we compare it with our profile.For the oven performance. We daily take a minimum of 3 profile for one oven. We have High mix low volume production. We are using ORH1 ( organic flux with halid cont

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

Hello! Don, Yes, if the carrier is steel/stainless, it would be very hot when it comes out from oven. I heard that durostone (synthetic stone) carrier can meet your requirement, it can stand high temperature with low thermal transmission. So when it
