Ralph Woodgate is the 'god of wave soldering process control.' We believe he is now retired, but in olden times his presentations at SMTA meetings were 'DO NOT MISS.' We imagine you can find his books on the used book market. Look here: http://use

That you can get good solder flow when hand soldering seems to indicate that the temperature of your solder pot is too low. Still, I'm uneasy that you see gold on the pads after passing the board across the solder pot. Gold is so thin with ENIG. So

does anyone know what environment factors(specifications?) and process control parameters(printer & reflow?) are optimal for running SMT using type 4 and type 5 solder paste respectively? Any pitfalls to avoid? The product we have been asked to use

Hello all! For my mechanical engineering study I want to etch a strain gauge in the Wheatstone bridge configuration in a copper layer of an PCB. The goal is to measure the strain occurring in an PCB even during the press process! We can measure with

I am currently finding it challenging(help!) to determine how I can introduce SPC ontrol within the AOI process and how the AOI can help control other SMT processes. Can someone please provide me with some ideas or any of excels fancy charts/macro

Sam, Like I said, AOI for pre-reflow inspections is the easiest to program and maintain. Each vendor of AOI has its pluses and minuses for programming and performance. Do a careful investigation of each vendor to learn about their machine performanc

I personally believe that you money is best spent on improving your process. An automated printer will help make your process more repeatable, thus easier to control. An AOI will not improve your quality, it will only make your defects easier to dete

We do have line configuration. EKRA E4, GL2, CP643, IP3, AOI 7550, BTUparagon150. What are the SPC tools used for SMD process control. I am looking for customized SPC software for trial to do process control on pre reflow, post reflow etc. any info ,

Hi Thanks, Going to APEX to see personal demos and hear what they offer and recommend is a great idea. I mean if you want to put AOI everyplace I am sure you will be supported with open arms. What I found interesting in the article was that large
