I think the datasleuths read might be the way to go this time around. I think my QE has a copy of Juran, so an SMT specific book might fill my immediate need better. Thanks for your invaluable input as usual, Dave. Since one of the changes in th

I listed this under design, but got no responses, so I'll try this forum. Our current solder paste vendor wants us to evaluate a paste. One of the selling points is that this paste (SnPb) will have the same flux package that will be used with some o

The size of a feeder is determined by the width of the carrier tape the components come in. i.e. If you measure the width of the tape with a precision ruler or calipers that measurement will be the feeder size. Also, when you order parts the tape siz

Hello all, I am having a problem with solder balls on chip resistors and chip capacitors. I have searched the archives and found some information concerning solder balls but have a couple more questions. 1. What is the realistic industry standard f

Hi! William, please check the new IPC-A-610 Rev C, para 12.4.10 for the soldeirng anomalies. Most of them may consider as process indicator and not the defect. The most common method to elimate the solder ball is to reduce the solder volume by red

Pete makes great points. Taking a slightly different angle, use your placement equipment's software to help you. It keeps track of the number of picks and attempts for each location. Study these numbers for a week and determine the capability of p

I used a Die feeder from Delaware Technologies for our Quad machine. We have not had Quad in our factory for over a year now so most of my knowledge is geared towards the older Quads. Don Dawson at Delaware Technologies can help. 609-235-8454. I am c

I know this subject has been beat to death, but I need a clarification. I keep getting mixed messages about how much gold is required on a PCB for a reliable solder joint. Some people are saying 3 - 5 microns, some are saying 3 - 5 micro inches. Do a
