Recomandation for purchase of SMT lines

Electronics Forum | Thu Jan 10 17:20:25 EST 2002 | Matt Kehoe

Dont forget, if you dont want to print paste and deal with the challenges of placing components in wet paste, solid solder deposit can save you the cost of the stencil printer, while offering better first pass yields than traditional methods. It just

Wave Soldering and Through Hole Forums

Electronics Forum | Tue Jan 22 13:19:33 EST 2002 | Shawn

I would like to find a site that is focused more toward through hole technology and wave soldering. This site has allot of helpful information regarding SMT but haven't seen much on wave soldering. If any one has a site or a link that they could pass

Solder Paste Inspection System.

The idea that AOI is not needed on your production line is like running a marathon without training before hand.You can only expect to get out of any given situations the amount from which you put in.Without some way of monitoring your process..How c

Wave Pallet Lifespan

Electronics Forum | Mon Jul 15 15:09:45 EDT 2002 | peterson

Hi all, I am trying to find some data that will show me the typical lifespan for a wave pallet. I realize that it depends on material used (Durapol, for instance) temp profile, etc and I HAVE checked the fine SMT archives... Anyone have an average n

Yield levels

Electronics Forum | Thu Jul 18 08:54:49 EDT 2002 | Mark S.

How do you capture the workmanship details on a "per joint" basis? I have recently implimented first pass yield in SMT but it is based on the whole part and not the number of joints. And yield is calculated by PCB failure rate..a PCB with a solder b

Height paste measurement

Electronics Forum | Tue Jul 23 11:14:16 EDT 2002 | juan_ruiz

We are interested on measuring height paste as a control method in our production lines, We are considering using a Cyberoptics equipment but we perform a GR&R for this equipment and it didn't pass it. Do you know a better alternative to measure heig

Component Lead Finish - Article in Japanese Can some body help ?

Hi, Europeon mandate has been passed to enforce lead free from June 2006 i guess. The japanese manufacturers have long implemented lead free and most of the component manufacturers have already gone lead free. I will post more specific links later.

Selective soldering pallets and solder balls

Electronics Forum | Wed Dec 04 09:24:52 EST 2002 | jseagle

I have found that preheating the solder pallets prior to use helps cut down on the solder balling. Also, we do not cool the pallets between passes and we use a spray fluxer because a hot pallet will knock down the head on a foam fluxer. We use WS f

No-clean paste flux v.s RMA solder

Electronics Forum | Wed Mar 12 09:23:56 EST 2003 | MA/NY DDave

Hi I don't see in your note any particular reasons why you couldn't. If it solders well and passes what ever specifications you are using than everything is OK. If your repair faces some soldering or rework challenges where a more agressive flux is
