Angela, besides the sense or non sense of six sigma and related meetings, you will have to break down the component feeding issue into several sections, which are all impacting the feeding reliability. 1. Component dimensions 2. Tape size 8, 12, 16

Dear Dave and Mike, I do not normally respond to threads of the forum. However, I do enjoy reading other's comments. There is a lot of valuable information provided by both suppliers and users. You seem to be making light of Bill Schreiber's com

Hi Kerry, I do not wish to turn this subject in to a debate, but consider this� If every technical question posted resulted in a commercial reply (company name, model number, phone number, price, features and benefits, etc), then there would be lit

Are you using a water based flux? Are the solder balls mainly around or near non-plated holes or near the edges of the PCB? If so the preheat must be set so the water content of the flux is fully evaporated before the board hits the solder wave. If

Are your voids looking like blow holes also? Is this only occurring on the solder joints of the Thru Hole components and Via's? Or does this happen on SMD pads? My experience is that we have seen this but only with some of our older PCB's which are

When you say all over the board, please give more detail. Where are they located? [All over wave soldered portion, laminate only, solder mask only, solder only, specific components only, etc] When you say white residue, what color are they really?

I have been using an MPAV and MVIIF for about 3 1/2 years and have had some difficulties, mainly with the MPAV. After only 2 1/2 years of use we had to replace the laser because we were having alot of QFP's being mismounted. That was an $8,000 expe

So much for the experts you asked for, Dreamer. Your project is fairly common. As an expample, there was a thread in the past month or two on SMTnet, where someone was looking for suppliers of "adapters". You should focus on: * Placing the adap

Your safest bet is to manually remove the trays. The problem with what you want is that the machine does not know that it missed a part. It simply goes to the point you specify and tries to pick somthing up; if it doesn't pick up anything it believes

We are currently using 0402 resistors and capacitors in our production process. Our equipment is as follows: - DEK 265 - Siemens S25/F5 - Vitronics XPM520(5 zones) - 2% silver solder Alpha WS678 The problem is that randomly some 0402 capacitors are
