Yup, that's the first thing I looked at, the pogo-pin block on the front, and where the motor plugs in. Both could be stress points. I will try resoldering those anyway, although they looked fine. I examined the rest of the board, too, and could n

We are currently producing a project that brings a TQFP64. But some boards do not solder the component well with its ideal fillet, some are well soldered when they come out of the reflow oven, but some are not. Can the pins be sulphated? How can we c

Thanks DWL, we have a board with double sided SMT components now. and there is an intrusive component on the bottom side which is build first. the connector pin is extending out by 0.3mm and this is causing printing issues when building top side. we

So wetting was unstable and slow . You need to do a wettability test to make sure about that defect .Also a material analysis to know the composition of the materials that constitute the components . if you get negative test results , you need to do

Attached is a good starting point. We also have Mydata and have had many different people providing names. Some used standard units, other metric. Try to stick with all metric and use prefixes that match up with the component type and pin count if

Also I should mention, I've ditched the formulas for getting the "optimal" solder amount after being bit by them once. Now I just design a PCB with 4-10 spots for the connector then order a stencil with a range of aperture sizes. Figure out what give

I am investigating the use of conductive epoxies to connect battery leads, Charging pins and wires inside small plastic housings. Soldering in these small spaces can create heat related defects in the plastics even when using low temp solders. Are

We have a similar board and came up with a quick and dirty solution. The board locates via pins onto a manual desk press with strategically placed feet to break the mouse bite. Not really much quicker than doing it all by hand, but after a thousand p

Also, be sure that your support pins are set correctly and do not allow the board to sag or bounce. Next, is your z correct? Its possible you are pushing the part so hard into the PCB that it's pushing back up or even bouncing the board and throwin
