Poor soldering on fine pitch?

Electronics Forum | Fri Jun 09 15:41:59 EDT 2006 | shawnvike

That is the problem I am having! Except with 3 separate manufacturers. To answer some of the other questions... Baking - diligence Stencil - as far as we can tell it is good Placement is good We are using Pb-free parts and solder, but I have see

Immersion Silver Board Finishes

Electronics Forum | Tue Jul 25 09:42:52 EDT 2006 | razor9114

Good morning, I got a question regarding Immersion Silver Board Finish. It has been imposed on us by our customer that we must manufacture PCB through the SMT process within 24 hours of breaking the seal on a bag of PCB containing Immersion Silver.

IF you are in the UK then you are probably best to run from that particular model at a bargain price. A huge number were released onto the market when a certain handset manufacturer shut down, and they hadn't exactly been cosseted. Quite a few comp

A flying probe tester is a mid-speed placement machine with no feeders and the placement heads replaced with manufacturing defects analyzer test probe activator head. It is useful for testing bare boards, first piece inspections, and low volume prod

using gold on PCB pads

Electronics Forum | Sat Jul 29 07:17:34 EDT 2006 | Ali Uzel

Hi all, I do know a little on PCB manufacturing. I would like to know whether using gold on PCB pads can cause soldering problems, both using automation and by hand. We are using a new device, 484-pin, 0.8mm, BGA and 0402 size capacitors. Or it can

0402 feeders

Electronics Forum | Wed Aug 02 17:19:49 EDT 2006 | flipit

Yes 0402 8X4 embossed feeders exist for Panasonic MSR, Universal GSM, Contact Systems, and Mimot for sure. In the old days of 0402 components, 0402 resistors used to come in 8X4 paper tape but now I think most 0402 resistors and capacitors come in 8

0402 feeders

Hi AJ, Just had a look though our parent company's stock on components, and even the smallest of diodes & transistors (such as DFN1006-2 package - roughly 0402)come on 8x4 plastic. All of the 8x2 pitch tapes are paper (EIA: 01005, 0201, 0402; JIS: 0

What is the name of the dross eliminator you are referring to? Who is the manufacturer? I went to your website and didn't see anything about it? I just ordered some MS2 from P. Kay Metal as I've been hearing some very good things about it from longti

SAC305 Solder Balling

Electronics Forum | Mon Aug 14 12:08:35 EDT 2006 | cuculi54986@yahoo.com

I agree with using the homeplate design on chips. Some Pb-free solder paste manufacturers recommend 1:1 apertures. This, in my experience, is not a good idea with any of the SAC305 pastes I've tried. I've been using the same stencil design guideli
