The results from an experiment comparing 27 different combinations of pad dimensions concluded that the pad design with 15 mil pad length, 12 mil pad width, and 9 mil pad separation produced the best assembly yields. A 5 mil thick laser cut stencil

Wave Cassettes and Heat convection

So others can solder the same board and part but you can't. Dipping the legs in flux doesn't help. Then it's either your pre-heat or wave. Measure your pre-heat and compare to others or flux mfger. Do you have chip wave or something like an Omega

Soldering robot and solder balls

Electronics Forum | Tue Jun 20 15:08:30 EDT 2017 | ranap121212

Hello I have the problem with selective soldering on the robot. Thin balls appear on the laminate. The tin sometimes shoots...? and then the balls are a few millimeters from the soldering point. I tried up or down with temperature, but it did not wor

SMT and TH board carrier

Is it feasible to have one type of board carriers to take boards thru 1) glue curing process for first side and 2)invert carriers with boards, and 3)reflowing second side, and 4) do manual stuffing of th components and 5) take them thru selective wav

Brian, We have the Mirtec Table Top. It is very good at detecting the component and orientation. It is however only as good as we program it to be. We have seen some limitations in respect to solder connections. I have not found it to be 100% re

Rework and repair system suggestions

Electronics Forum | Thu Jan 27 11:33:59 EST 2005 | russ

For what you have right now I would recommend that you use soldering iron tips that are made for component removal. until you get BGAs I wouldn't worry a whole lot about the expensive rework equipment. I would use specialty tips and a heat gun wit

Guys, So I recently started working for a small CM in Southern N.H. We currently use 2 Magic Chef Mini wine friges to store the solder paste (63/37, RoHS). I've been monitoring the room temp (and humidity) and the frige temps all this week. The pro

| Has anyone had experience with placing BGA on gold plated boards. I thought I read a while ago there was a problem with embrittlment causing cracked joints. If anyone has experience with this your feedback would be great. | Mike Mike, We and ind
