I've never seen this before and I would be suspicious. Have you tried to dust it off with a brush or Q-tip, it might just be some sort of process contamination. Have you looked at the reel to see if the parts are coming in with these spots from the

Hello! Recently started buying PCBs with peelable mask to remove the need for Kapton tape. Had no issues with our first batch, but our supplier has over-cured the second batch - it comes off in tiny bits, and is stuck in the holes. After timing the

I have used the Chinese ovens that Manncorp is selling bought from another supplier and they can do the job. These will do the job. You can manufacture metal piece(plate) slightly tilted to collect the boards behind the oven(similar to wave soldering

Wave soldering inspection templates enhance the visual inspection process by guiding the operator's eyes to a specific location on the board to check for the presence and correctness of components. I feel that PCB visual inspection template should be

I'm having a problem getting sufficient solder reflow on a SMD part. The board design (which can't be changed) is covered in ground planes that cause a lot of uneven heat distribution. I believe heat is wicking away from the culprit part, causing t

Hello, We have recently bought ZipaTec select 250, we are having problems with offsets. Somehow the offset of fluxer, wave and preheat dont match one another or the program we create. The previous owners are of no help. The main question i have
