I am in the R&D department at KIC. We have been making thermal profiling equipment for 20+ years. A standard circuit board is made from FR4 fiberglass. A typical solder reflow profile, whether leaded or unleaded, takes the board above the "glass t

It sounds like you may be thinking of two different test methodologies. What is required? Bare-bard testing, to verify pcb fabrication? Or populated board testing, to verify manufacturing? If it's bare board testing, the fab house should advise a

| I'm trying to find a source for a tilt device for use when doing touch-up soldering. Employee needs to raise the board above standard bench height for better access to the board and for better posture. Angle of the tilt device should be adjustabl

That 60+% print defects number has been bantied around for so long in the electronic assembly business for so long that people believe that it's true. One starting point for this myth and lore is: "Where Quality Is Lost On SMT Boards" C Mangin, 'Cir

Q1.� is it mondatory to test all components and paths in the PCBA; and check all soldering joints? A1. Nothing is mandatory. You do ICT to prove some component functionality and check manufacturing process. ICT test coverage is driven by factors i

Believe it! Although it might be necessary in certain rare cases, and as Ray says, as a bandaid, to routinely bake your boards is a mistake. For much more info, search the IPC technet archives over the last few weeks. It was a popular thread

Amazing in today's technology that people still bake because "that's the way we've alawys done it". Baking is a band aid for poor manufacturing of the PCB. Moisture can become trapped between the layers during buildup. This moisture when it contacts

If your flex circuit is only populated on one side, you can have the PCB vendor palletize the flex for you. What you do is have the flex circuit laminated to 062" FR4 using a thermoset adhesive like Dupont WA. Standard flex circuit adhesive. Howev
