I purchased the JW-3040 manual printer after seeing this company here. They were advertising the JW-3040 as new but their website said they specialize in used products. I specifically asked and was assured that the printer is new and comes with a squ

Hi All, I have been looking in to some failures of PCB's in Assembly. After SMT the boards are stored for different periods of time in high humity environment (72% RH and 21.4 degrees Celsius) before being sent to Assembly to be handsoldered/put thr

Hello, Manufacturing process with high moisture and humidity environments and long term storage will definitely see pop corning effects once high temperature from soldering and/or re-flow process. The moisture that has been adsorbed is likely the ro

With a melting point of roughly 300°C, you would need to have the product see temperatures peaking around 325°C at a minimum. (I would make sure the components and PCB materials can withstand these temperatures) Most convection ovens do not go over 3

We do a lot of low volume prototypes and several boards that have have cut outs or fixtures that dont always reliably stop squarely at the in carrier (beveled corners). This sometimes results in a fid read error, because the fid wont be in the search

Yes, your picture is correct. Regarding the dichroic mirrored prism assembly…in this application, a dichroic material is one which causes visible light to be split up into distinct beams of different wavelengths. The original meaning of dichroic, fro

I'll try to deal with the issues as you've presented them. 1. Blistering/delamination, shown in photo 2. The most likely cause of blistering/delamination like this is moisture in the boards. The moisture can get into the boards in multiple ways..

PCB Manufacturing demands preparation of design well in advance. The finalized designs are fed into the systems and the production is carried away. If the boards are of small sizes, multiple boards are made on a single large board and separated into

We have new stencils produced every 15000 prints. Another technician takes care of that and he uses gerber files to have them produced. Also, we have over 300 different products that are produced, all board sizes are standardized 287mm long x either

Hi evreybody I wish to know if somebody can describe how is made a "Calibration Slug" for centering the upward camera of a QUAD IVC machine. The instruction manual mentions a slug that is attached with vacuum to the "Vision Nozzle" and there is some
