Acquire a fast dispensing machine that can deposit solder paste to keep a low volume pick and place machine working. This would save us two things: 1) Stencil delivery waiting period for customers who bring with them their PCBs fabricated in the loca

Basem, I can't direct you to a dispensing machine, as I'm not familiar with them. But, I can tell you what we do. We specialize in short volume, prototype quantity runs. Since prototypes and short quantities are not conducive to volume operations

Dstadem, Thanks for bringing your in valuable experience with the J STD 005 " Requirements of Solder Paste". I fully agree with you that the Solder Paste can be qualified for shelf life by doing simple viscosity test and visual inspection for coal

Traceability can be made for many things. It is up to the factory and what it wants to implement. You can have traceability on the stencil for a several reasons: 1. Want to check stencil cycles 2. Want to verify if stencil is the correct one loaded 3

Hello, the colleagues are all right. What I did in addition to show customers and quality that we either need or dont need a stencil: 1. Made a procedure - in there i defined 50 000 cycles and then the stencil has to be checked by me. In the checks

I agree with you. I just said, if it is customer requirement, factory has to implement it, right? :) Of course it is huge amount of money. SPI is the main control, but it doesnt save you the pressure, speed, snap of from the printer to the trace (us

For a modest invest of capitol equipment and maybe some hair pulling to learn the process it shouldn't be terribly difficult to get your own production line up and running. You just missed a few trade shows that you could have went to and seen all t

We normally disregard what the "tech" sheets say. A lot of it has to do with your printer settings, prints per hour, placement time, stencil cleaning procedures etc... Just another wrench to throw in, We have noticed lot to lot paste differences al

You may struggle finding the information that you seek, because there is so much variability in the design and fabrication of boards. * What is the purpose of such a test? * What product type sees such an use environment? Consider using the guidelin
