Hole size may not have been an issue for you because your holes were already big enough? The alloy you are using has a lot to do with this I believe also. We are already at 5 seconds dwell for this which is mfg recommended for our solder. The caps we

No, the thicker plating and need for very high quality drilling and plating is DUE to the higher copper dissolution rate and higher contact time. As to the Sn100C material, their claims seem to confirm a "lower" copper dissolution rate, but so does A

I looked at the Kiss104 and the SPA-400 at the SMTA show in Orlando. I spent an hour with the ACE rep, and walked away totally confused as to how the machine is programmed. I spent 10 minutes with the rep from APS Novastar, and using their Photoscan

Do you have any input as to the vibrations seen on the end-use device? Types of device(s) that have solder joint failure? How many thermal cycles the PCB goes through before failure? There are several areas in production of the board that could be th

I thought you said that the parts that weren't wetting in reflow were the parts with epoxy. The question I have is do they wet in wave solder, and if they do, why does it matter what happens to them in reflow? Conversely, if they don't wet in wave,

A recent thread regarding the ACE KISS equipment has me wondering if anyone is happy with their choice in selective equipment. I don't see much mentioned about Pillarhouse, Juki, ERSA and some of the others. We're currently debating whether to inve

Thanks, rywman. I do have a solder sample along with dummy BGA's so we should have what we need. This BGA is actually 1152 pins (I didn't have that right in my original post). The bad part is that we are building only one board only and the actua

CC True enough, indisputable and factual...my whole point was that there was NO communication from the company(s) or the peddlers on the subject, causing an unimaginable number of wave operators, engineers, production managers and CUSTOMERS to pull o

Whoa dude - slow down- maybe great beer money but if you don't have good environmental and ESD controls in your shed, all your suds slush fund will evaporate in RMA's costs. A small pick and place (table top) would do. A manual screen printer would h
