Double-check me on this, but I don't believe that A-610 [IPC-A-610] requires side fillets on QFN solder connections, because the sides of most terminations are not plated. Plating on the bottom of the termination is sufficient for a proper solder con

Hi Sam, The skewed part images I have shared at my first Query. We have excluded other causes because, We have faced this issue in one particular oven. Where as this is running for many years in other oven lines and we don't have this issue. So ot

Hi Ed, These images contributed to my coming to that conclusion. Question, in case you have an answer for this. In your experience, do these kinds of defects exhibit much latency or are they usually found early if they exist at all? I ask becaus

Hello Everybody, I have a Siplace S20 machine which make X axis counting error. I replaced the sensor, scale and all the parts are good. It seems to be measuring error because the machine do measing error if the X axe move to much. Do somebody have

Dear fellow assemblers. Need help to locate program for Flextek buffer (end of the line). Our unit lost battery power inside of PLC CPU unit (SLC 5/03) and now it lost program inside I believe because it shows Time Out at the time of initialization a

Flexible circuits assembly is different from rigid board assembly. For some manfacturers, fpc assembly are some things more painful because the assembly quality is unstable. Recommend to check and hope these 2 blogs are helpful. Flexible Circuit Asse

It turned out that only SF heads support "fine" mode, while FNC does not. Probably because above the FNC nozzle there is a "circle" rotating the nozzles, and in fine mode it can interfere with the reflection of the camera light - the element is lower

flux my leave a white residues even after cleaning, when we want to select a flux for our Ersa Ecoslect we tryed a varity of fluxes (including the IF2005C) and we decide to use the Cobar 390-RX-HT because he gaved us the best results in soldering and

Kyleh04, I worked for one place that used the vent inside the building. You end up with a lot of heat, smell and increased number if defects(because of the heat in the building). Based on the debit of your machines you can can combine them and use a

Do you have clear picture show how it looks like solder open? And you can run DOE with TAL and soak time and peak temperature to see which factor is key, or non of them is key then you can try add some flux to see if better before change solder past
