Boots: Here's several methods for guessing at the amount of solder on your connection: * First, 'Down & Dirty' ** Assume that the solder is flat, which is reasonable since it's 'flattened' by the component package ** Assume 100% paste transfer from t

If you are developing a cost model for quotation/estimation purposes, we would recommend time studying a handful of existing jobs/set up's that you have, and averaging your actual CPM rate. Then determining your cost to operate from there. This wil

In answer to your question no. Fiducials should always be as far apart from each other in both directions (X,Y) as possible. This will allow ANY placement machine to calculate the EXACT location and rotation of the PCB, and therefore correct the moun

Thanks Alexei for your advice. I consider mainly high-volume production with tape/reel feeders for most components and tray for big ICs. My ultimate goal is a cost estimation of the production activities. So departing from a parts-list, I need to est

Sorry I didn't catch your message sooner! 20k is way to much. The odds of you having 3 bad platens and 3 bad forcer motors would be very unlikely, unless the machine was sitting outside or something. If it is a 10 year old AP then I assume it must

I'm mostly looking at the time so that I can schedule. Basically I'm looking at running 1000 panels of project A and then 500 of project B. I have a limited time to get a portion of both A and B to the customer. What I am trying to confirm is whether

Where is the best place to get exact dimensions for waffel trays? The trays themselves give the support dimensions n each pocket, but as you know, having the exact pitch makes it quicker to program a tray,by eliminating the measuring and estimating o

Can anyone tell me the cost or estimated cost of soldering BGA's to the PCB (per package, per ball)?? Also, is there a similar cost for Rework
