Incoming inspection: Look for flaws and measure position of v-score as well as depth. If v-scored on both sides of panel, make sure v-scores are in alignment. Follow the PCB thru all processes inspecting after each stage of processing, especially

SWAG has it. Carriers for SMT are a great idea, especially to mitigate sag, and allow some savings in setup. Fixturing setup advantage: You could fixture everything to a fixed width, and eliminate rail setups throughout your lines. Trade off the f

I didn't even think of running a blade down those scores. I will give it a shot and see. The laminate they're using is Nanya NP-140, if anyone has ever used it or has any info regarding it's issues around something like this. We can see resin weave

Do I need to lower temperature of bottom zone (for common size parts) while reflow 2nd side of the board or I should be using same profile as I used for 1st side reflow? Will parts on bottom side will stay in place without changing temperature?

I don't think you decide that based on the oven. More important is what kind of parts you have on the board. If you have big heavy parts you should run them as second side.Of course you have the option to put glue under the suspicious part and run it

I'm not positive, but it looks like it could be a multilayer chip capacitor with the end metalization on the long side. They do exist: http://www.mouser.com/ProductDetail/AVX/0612YC105KAT2A/?qs=sGAEpiMZZMukHu%252bjC5l7YbS7Gp8EQB5AtLAgTHK6PsA%3d

Hi, We had experienced very similar issue on boards of a certain PCB manufacturer. Field experiments showed that the solder mask of this manufacturer is prone to swelling and peeling after it was in contact with our water-based flux. When you switc

Yes, jsd.jwww it can be seen right after reflow. I read back thru the spec sheet and under "soldering conditions" is says "temp. at cap surface" so thanks, SteveO I think you hit the nail on the head and we'll have to revisit the profile and target

I would love to use my old zevatech with a large nozzle (qfp) to pick kapton masking dots and place them on a board. I am getting some 'thicker' kapton dots to test, and need to find a way to present them, might be a trick but worth a try. Has anyon
