By far the easiest way is to track solder paste measurement on your board - or solder defects after reflow (key word- easiest). Why spend 2 weeks examining a stencil when it clearly doesn't make defects, or IS making defects. I find using 2-D data

Hi, I would agree. We purchased a TP9 just the slow machine, but we were a small company at the time, and it worked fantastic. Almost no maintenance, and it's a dream to changeover. The serivce in Australia is also very good, but that does not appl

Similar to my response to your previous posting on this topic dated 5/8/01, things to try are: 1 Contact your non-supplier [Streckfuss] using the contact points at http://www.streckfuss.com/wave_soldering.htm, obtain source drawings for components o

Hi, I put this on the technet forum, and I know some of the same people are here, but I thought I might catch others here as well. We have PCB's which are populated at the CM level with no-clean solder paste. However in house we use a solder wire s

Hi mate, no complete info given from what i see, so just some humble comments, mayhaps you review : 1) PCB pad finishing - Copper+nickle plated? coz if so, nickle is a KILLER to good solder wetting. what we did back here, was to HAL coat the nickle

Thanks Dave. We develop high-speed telecom PCB assemblies that use uBGA and other fine pitch components. Our policy has been to use an NC process at our CM. Our engineering group, who is also a customer, and uses these assemblies for development,

I read your request for design information on panel layout for V-scoring, and felt the need to respond. Scored PWB's are indeed more efficient to produce and depanel than tab routed PWB's, but there are also drawbacks associated with this method. T

There are several things to look for in a compliant tooling system 1. How much force per pin is required to lock the pins in place? This is especially important since you will be multiplying by the total number of pins on all modules. 2. Is ther
