We want a dedicated machine because we have some concerns with SMT adhesive residue that is in the bath contaminating boards. We are getting pretty heavy into class 3 so everything has to be pretty much perfect. We run 2 shifts and have 5 lines so w

Hi all, I'm having issues placing 7 pin DPak packages. I'm using mechanical centering with four centering phases (one for each orientation). Tool used is A24S. Machine picks up the part but will reject it when centering the part. I have measured all

Nitrogen in Reflow is grossly over-rated...., in my opinion, and in the opinion of several very well known SMT Industry "God Fathers". Way too much $$$, for a slight increase in the process window. If you profile your oven specifically for your pr

We are currently experiencing thermal shock failure on a BGA package. We are currently looking at improvements to improve the thermal shock properties by using underfilm. I have seen some studies out there that use this process to improve drop test

Hola I have this connector (atached image) for Wave Solder process, there is one pin with no solder on the top, for me it seems that the large trace connected to that pin is "stealing" the heat... I'm not WS expert... can it be corrected by profile?

You might consider to contact a lab to Run a microindenter against a know good soft gold sample. The knoop value for the soft gold will be much lower than for hard gold. This would be reflected in the diameter measurement of the indented samples.Smal

SMTnet colleagues, I am looking for your opinions on the PCB/CCA cleaning process. Regardless of fluxes or population complexity I want your opinion on these three cleaning processes and what you consider to be the best for what and why. Thanks for

I am sick of Kapton. We have varying levels of leftover residues on multiple brands and I'm done chasing this thing. We have tested some wave tapes that were total garbage in years past. Really don't want to go there. Peelable liquid masks - Who
