Vlad, That was a bad statement to make... Enig should never be thicker than 5 micro inches max. or it will cause embrittlement. This process does self limit but it can put on as much as 10-14 Micro inches which would be a major cause of concern.

Hi, Our Fuji CP6 table is rising up abruptly when it unloads a pcb after populating it. It makes a clunking noise much louder than before. I don't see anything that has changed or gets in the way as far as the table rails lining up with the exit c

Hello Hoss, try with the flux again. I would first change the flux. Alcohol based for me is always better. But you can try water based too. 1. Change the flux 2. Go with more pressure on your atomizer(or whatever they call it on your machine). Just

Steve, I finally played with it enough that it is working again. I ended up with Edge Threshold: 19; Intensity Threshold: 60; Offset: 200; Gain: 16 The problem seemed to be with the Intensity Threshold. I was not getting an error code on the screen

Hi Steve, Are you actually profiling the BGA itself? By that I mean have you, for example, drilled through the underside of the pcb into the balls of the BGA and attached a probe there? You may find that even although the topside components have a p

SMT-ypw: Does PWB supplier start to implement PWB drying packaging? B3: YES! The fabrication of the PCB involves a series of wet processing that requires counter-measures to remove moisure. While some of the PCB processes also include bake cycles th

On TH parts we have been hand soldering. This last summer we purchased a Rhythm selective solder machine from RPS automation. I did a factory tour of both RPS and ACE since both facilities are about 1/2 mile from each other. In comparing the 2 c

Oops...just noticed you were referring to wave soldering. We'd still suggest a water-soluble flux, instead of the no-clean; especially at wave soldering. Also, checking pre-heat temps, and dwell time on the pot. Is the wave a chipper wave? If not
