Hello everyone out there in the SMT world. I have a dilema I'm currently running a board that has 3 csp's with a .75 mm. ball pitch and .3mm ball size. And 2 qfp's-160. The stencil is 4 mils thick and I'm using a 63/37 solder paste. My reflow prof

We used this type of paste in a fine pitch application for over two years with no problems. You must be very careful of any (dust)or spillage while mixing for obvious reasons. In my opion the very thing that makes it interesting "freshness" is also i

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

Hi, undercured solder resists may be a defect people have seen so far. Some of the probles arising is blistering as well as reaction with wave solder flux that may lead to some kind bad gel like formations. Gels the idea would be to reflow the ba

Any decent 7-zone reflow oven rated at 300 degrees C will handle lead free. Prices for used ovens in this range begin around $15K. For waves, the prices are all over the map. Send me a private e-mail and I'll introduce you to a friend of mine who sel

Hey - remember the evaluation of VOC-Free fluxes that I promised a couple of months ago? well, I finally scrounged up the time to remove the propreitary (board name and number) info from the report. So it's ready. I posted it in the SMTnet library
