If I had my way - the person checking the incoming kit should be able to at least run, troubleshoot and preferably programme the SMT line. In fact they should be an expert.They have the paper work in front of them for that job. If the tape is cut - t

Has any one considered the melting eutectic of the plated part verses the eutectic of the paste it self. Inter metallic solids can form when mixing metals. Thus this causes solder joint reliability. Also a lot of vendors are putting out pure tin prod

Hi, What studies? Can you post a link? I am not sure what the difference is between a ceramic BGA that the high temp solder ball is not expected to collapse, and a lead free solder ball that's run through a lead process and also does not collapse b

AMS, Are you aware that you will have to purchase several types of insertion equipment for different part types? You will need an axial inserter, radaial and DIP inserter to cover the gamut of thru-hole insertion. Even then you may not cover oddba

Establish a profile board. It should be representative of what you normally run on a daily basis, size and parts wise. Attach dedicated thermalcouples so they are permanent and will not move or come loose. High temp solder is best. Establish a pr

If you want to be able to put down every type of part, and fast, you better look at buying two machines. You did not say how much speed you need but in-line spindle machines rely on gang picks to be able to come anywhere close to rated speed. I have

Unfortunately it's not what you know, but who you know. Sounds like it in your case. Tread lightly as this guy may become your boss. It happened to me. New guy comes in, couldn't tell the "red stuff" from the "gray stuff" (adhesive / paste in cas

Do the math first. 10,000 boards a month means 440 boards a day (roughly, and not including weekends). Do you plan 2 shifts or only one? If one, you need to produce a board about every minute if you work an 8 hour shift. If all 110 parts are on on

Hi, It's hard to tell what exactly is wrong, as I personally never used the older software only the Linix based version of the machine we had. In fact when we got out machine, it was ex demo, and the sales guy said we really needed to get it changed

Hi all, At our Fuji CP-6 machines we place a lot of 0402:s, 0603:s and 0805:s chip capacitors. Our problem is that the height of the components can sometime be very extreme from different vendors. I am sure you all have experience of this phenomenon
