I'm having a problem getting sufficient solder reflow on a SMD part. The board design (which can't be changed) is covered in ground planes that cause a lot of uneven heat distribution. I believe heat is wicking away from the culprit part, causing t

I had similar issue on S20 two times. The portal2/gantry2 have camera image? Have working camera system - if other camera ok, PCB camera will be the problem. Have camera screen on BE/Components camera? Have iCOS PC working. - Check the camera conn

Thank's Dennis. I'm also now think in this direction. Process was adjusted and soldering are good. But one from five boards can have this effect with bubbles and strange uneven distribution of solder inside the barrel. Probably copper is too thin and

Erwin, I have a question for you. Are there any dross recycling facilities in the Phillippines? How much do they pay per lb/kg? What is your cost of solder? If you recover 75% good solder from your waste, you can easily cut your cost of soldering

Hi Anthony! Earl's right, things can get rather involved when you start discussing ALL the things that affect whether or not a board is going to warp. The way I look at the issue is try to separate the warp issue into two catagories; 1. The board bei
