Hi, We place BGA, but until now have not used X-Ray inspection, and it would be a good thing to have. Can anyone recommend a low cost X-Ray that would get us by. We don't need something fast, but it should be able to show us clearly voids etc. Reg

We evaluated several machines a couple of years ago and ended up selecting an Agilent SJ50. Fast machine but very limited on joint inspection. Also does not detect missing components reliably which you would normally take as a given on an AOI system.

Hi, I think that the time depends on the type of stainless steel, temperature and solder alloy. For example, one of our machines is delivered with 316 stainless pot and alloy SnNi. It worked six months (120days*16hours = 1920hours) and aft

Many of the components will deteriorate at very different rates. This makes giving an hour rating difficult. If you read, http://www.speedlinetech.com/docs/EquipmentImpactsofLeadFreeWavesolderingAPEX2003BestUSPaper.pdf you will see they give inspe

You haven't mentioned whether you are producting only through hole product or if it is mixed technology. What kind of flux (no clean, H2O clean) you are using and whether you performed a first article at part stuffing prior to wave. Generally, you

Per Bob Willis, the UK based guru of all things lead-free: "The only thing those swabs do effectively is lighten your wallet." Really, they don't work reliably at all. You are better off trying to do it by visual inspection. I've tried out an XRF

We sometimes use a peelable mask the the PCB manufacturer (board house) adds as part of their process. It may seem an expensive option but avoids: Raising P/o's for tape/peelable mask as consumables booking & inspection Booking out to the shop floo

We recently had some boards returned that have me stumped. Word was QFP pins were coming out of the solder in the field. Upon inspection it was true!! If you press gently on the pins they SLIDE out of the joint. The joints look good, shiny ect but it

I couldn't find any sanctioned procedure for dragging a pick across the leads to check for opens. I've never been a big fan of this anyways. Other than visually inspecting under a microscope and touching the leads that look suspect is there anything
