Pardon the cross-post from the design board....I thought maybe I should query both populations. Is anyone out there aware of any standard or even a section of a standard that specifically addresses design guidelines for two-sided assemblies, particu

Hello all, Dave, this is just another example of how your attitude towards others in the forum, outweighs your open mindedness toward their right to participate....It's SMTnet....not DAVENET. I'm not surprised to see you try to quantify the validit

An effective method to compare the two machines is to go to each vendor's nearest demo facility. Go there with PWBs, components and board data. Find out from each vendor what the minimum board data they'll need- like X-Y Centroid, Theta and Reference

Quad4C's have their moments. If the price is right and you are aware of the machines limitations then you will be satisfied. The placement rate is slow, 1.2 seconds/chip. Don't buy any Quad if it has the CyberOptics Laser unit, the Quadalign unit is

Traditional methods of hand assembly are as you described. For a company that is concentrating on the 1-5 or 5-50 quantities you've described, you need to look for ways to accomplish your task with speed, repeatablilty, quality and at a fair price. T

I need some input on what good solder thieves dimensions should be. I am limited to solving my bridging problem with solder thieves; all process/wave variables have been adjusted to try to solve this problem. There are several of these connectors on

Dave, thanks for the info. This sounds like it would verify the presence of an open. We have verified that these balls are open and I am trying to figure out if we are fracturing or not wetting. causing these opens. I would use the die method on ne
