We need to be careful with product to avoid introducing a new failure mode, namely corrosion and dendrite growth, especially those running no clean processes! In addition to heat (reflow, wave and some selective soldering processes) killing the vi

Furlongs? won't that be confusing and leave a lot to interpretation? Question: How long do you want it fur? Answer: 6 months, the unit will be obolete by then. and let's not forget the Animal Rights activists, they will have a field day if they beg

The actual water soluble process is killing us. We sent the cloose loop tanks for regenaration each two weeks. We spent too much money sending the tank overseas. Is there a company in PR that recycles this tanks. Maybe in Florida? What is the low

Sounds like you're killing the poor little critters. Tell us about: * Placement force. * Reflow method. * Where and how you are measuring your reflow recipe. * Cooling rate of the reflow recipe. * How the solder connection to the metalization appear

We are using a Hoverdavis feeder to place labels with our GSM's. The labels we are currently using are .650 x .250. We have had it for a few months now and, so far it has proven to be an excellent buy. Placing thousands of labels by hand was killin

We had a contract in house that included a flex board which required an 18 hour bake at 105 degrees. The other brds got along fine with 2 hours, but the flex board would delaminate until we went to this long bake. I don't know how the engineer came

I would be willing to bet that you are ramping up way too fast and possibly too hot/long of a soak and killing your flux activity. this will give the appearance of "no reflow" due to non-coalescence of the solder balls. check this board with the hel

Hi, We have a board with over 100 chips (mixed size) and some long Connector DIP through out Wave solder with many issues of no solder and solder bridge, (using clean flux with bubble fluxer and Kester solder bar). Currently we tried to reduce the de
