I have been using overall combined DPMO of SMT PCBAs as a performance metric. All defects are recorded down to component location and defect category. The resultant defect data table is analyzed with detailed pivot tables, defect type and defect loca

Thanks Nance. So, your production process is: * Screen / dispense glue on secondary side * Place secondary side SMT components * Cure glue * Insert primary side PTH components * Wave secondary side Please tell us about: * Flux type and wave s

My question is concerning a cheap PCB material. I have a sample with me and I have to quote on this product with the same PCB material. This material is not FR4 and the color is beige. I think CEM-1 material is beige too but I`m not sure. I`ve hea

| Does anyone have any experience they are willing to share on Ag epoxy used as a copper through hole plating replacement? Was CEM3 used? | What are the limitations? | Thanks, | Steve I have used silver epoxy extensively for conductive bonding applic

You should do some testing what temp you really get. Solder will melt 260~300ºC. Back to the initial question, CEM-3 is a bit harder to buy and has not many varieties. Go for FR4, you can go for a higher Tg then the common 130ºC. There is also 140,

Where can I find laminates containing non-halogenated PCB? I'm especially interested in FR-4 and CEM-3, 1.6 mm 25um. Thanks in advance! Dr. Lennart Johansson Polymer Support

Our CEM running No clean process on our PCBAs Should we verify that he is using the Deionized water rinsing or is it a default in the process ?

As I transfer prototypes/pilots out of my shop (because the designs are mature or Engineering confidence is high). How do I minimize my risk and ensure success for both the CEM and my group. This would include low tech as well as higher tech boards

Hi, I work for a UK based CEM, I am looking to source some blank Universal VCD toolplates, for a dual head machine. The company we used to purchase the plates from has folded (EES and Amps) and we are looking for a new supplier, any ideas. G
