Hi Dilbert We manufacture equipment for the electronics industry. The holy grail "guide book" you looking for does not really exist. I wish it did. I got with our compliance engineer this morning for help explain since I am not that experienced i

There are many low cost paste inspection systems on the market today. It really depends upon your overall needs for process improvement. The CyberOptics LSM series of inspection devices use a single laser stripe to calculate both Height, Area and V

Electronics manufacturing moving to China is not about the labor man. You all don�t get it. It�s the material, and not just the electronics material either. Plastics and metal parts costs are lower. Labor costs are the smallest component of a produc

This is a very difficult question to answer as it will depend greatly on your component mix. I will presume that the CSM 84VZ is of the following configuration: 2 x RDC Synchro Heads. Heads 1 & 2. These are mechanically centering heads with a chucki

These ones from ALTERA the QFFP-304 0.5mm weight: 32gr. used to give us a really headache in the past. Not only soldering issue:s but also the placement in x-y-theta! The stencil thickness of ours is 0.13mm and because of ohter compomponent packages,

I'll respond to this one since it is the most poignant post in this thread: ------------------------------------------------------ Most of what follows is common sense, but sometimes we need to get grounded to remember these common sense things. ---

By the way you asked the question, we assume that by "reballing" you mean bumping, we should be able to figure that out: * Volume of the ball = ( pi*d^�)/6 = [355/113] *0.6*0.6*0.6]/6 = 0.11mm^3 * Volume of solder required = 2*volume of ball = 2*0.11

1. can you load cut tape onto the feeders, or only reels? You can, but you have to use cover tape extender (pretty cheap, though) >2. how about parts on trays (like Atmel AVRs in the QFP package)? You need tray feeder. But you can "make" your own
