| We might be doing a job with some plcc, soic on one side and the other side will have two BGA's. Does any one have any ideas on what knid of problems that might occur if we reflowed both sides? Like heat temp, surface tension, etc. Thanks for any h

My company is looking for higher density for card layout. One suggestion has been locating active components packaged in SOT's and SOIC's on the B-side of the card. This in turn will require wave soldering of the above mentioned components. When I di

First of all ask your Suplliers to provide you SMD in Tape & reel, second point, you can ask Service for Tape & Reel or in case components are not so many, you could asses ef convenient to buy a sinple maual Tape & Ree machine and do it inside your f

If it were other machines I would suggest the possibility of air kiss blowing the solder away, but mydata's have a release to make sure the air kiss never gets too high. Unless it is not pointing 90 degrees away from the machine like mydata recommend

Agree!! Where is Your thermocouple-probes attacded and can we get the info from this? Delta-T of the comp. is very, very important! The single most important smt-process step is the profiling/recipy and as a result of this, this poor package will cor

Hi John, Depending on your board, it could make a difference. Copper finishes might leave that part of the pad exposed, which is a no-no in most places. Where as a HASL board prolly won't care if you pulled the print back. On the other end, over

0.700. What is special about 0.700? My part is an SOLIC14, which has a length of 0.350. So 0.700 is exactly twice the length of the part. Is there a problem feeding a part from a vibratory feeder if the escapement length is more that twice the lengt

Based on your knowledge and experience, could you tell me about speed differences when placing a mix of SMD at mass production? We could consider packages like the small R & C chips, then SOD323, SOT-23, SOT-23-5, SOT23-6, SON6, QFN8, SOIC-8, SOIC-16

Pete: It sound like somewhere through all that you should have gotten good product. Here�s a couple of questions on your board: * How are the SOIC positioned relative to the wave? * How are you controlling the flatness of the second wave? * What
