I have a customer working on a new design of a rather large board that needs to use a micro BGA that will require 8 layers. He needs to use that BGA and it does not come in any other package. He asked me about making the BGA an adapter or daughter bo

Good Morning Stephen, 1) Most solder paste manufacturers recommend a 2 hour temperature stabilazation period. Solder paste should not be opened and exposed to ambient air if it is still cold. 2)Manufacturers do not reccomend mixing old and new paste

I'm probably not telling you anything you don't already know, but a technique that's worked very well in the past for me is to methodically step through every part of the process and observe your boards being built, or take a scrap or simulated one a

Hoping someone can help us. Our Fuji IP-1 won't boot up unless we disconnect the 25 pin RS232 connector that runs to the MCS16/F programming computer. It doesn't matter if the 9 pin connector on the other end of the cable is plugged into the MCS16/

What about the component placement with Head #2? Head # 1 is ok? Is it only the pickup that is the problem and if so, from all feeder banks (front & Rear)? Concider Z-axis height adjustment, procedure is in the manual. You normally don't need to re-

Russ We agree with your comments on plugging from one side only. But... We believe that it IS possible to trap process chemicals [technically, not flux] in a blind [or any other] via. This can be done by plating the via closed, rather than pluggi

Ideally? Never. You risk component break down by re-running the board over the wave machine. In a perfect world, your wave operator would make adjustments after one run, and you'd run another panel over the wave to judge the effectiveness of the a

Hi, If your doing a line, then your going to need more than the simple prototyping machines listed above in this thread. (Although they are cool ideas, and loved the toaster oven modification guy, and the other guy soldering ic's with it too!) We a

I placed a Maxim MAX16810 38 pin TQFN with a power pad ground on the bottom of the chip on a prototype board FR4 doble sided. Vias of 0.6 mm where placed underneath part, 6 vias in total. Solder was placed with an air operated syringe, land pattern w

We're currently running a manncorp ECM-93, which has served us alright, but we've pretty much outgrown it. We manufacture power electronics, a lot of double sided designs with odd form parts. We have about 30 different designs we manufacture, and we
