Problem is I don't have a mesh belt (lesson learned). Our conveyor is pins. If I laid some scrap pcb's spanning the conveyor pins on the long dimension of the board, I'm confident it would sag. We get a bit of sag today in our 1.6mm thick boards whi

Thank you, Mr Dave. Specifically, there are tiny balls spreading on the boards ( on top of solder resists, and not encapsulated). They are not near to any land/pad or connector. I do not think they post any electrical problem. They are quite far away

Ball Grid Array (BGA). A surface mount technology leadless package with the connectors to the board placed in an array on the bottom of the package. They are attached to the board with tiny balls of solder placed on each contact. Pin Grid Array (P

Hello everyone, I am currently running a gold plated SMT board and am experiencing tiny solder balls between the pads and the masking between the 20 mil pitch devices. I'm looking at these boards with a 60x microscope. IPC-610 say's any visible solde

Since the inductor is electro-magnetic, that means the device is composite of coil and ferrite metal. The inductor inside the reflow oven meets with blower motors which close to the inductor and generate magnetic field. With such conditions, Lawren

I am four weeks into my new job, there always seems to be some issues here with PCB every week. Today while I was checking some assemblies with micro-scope, I found a lot of tiny bubbles/blisters on the board. They are just little dots if you look

Hello gurus, I am a hardware designer with a small company. We are about to send a new PCB for fabrication. This board uses dozens of tiny QFN, DFN, and similar packages. As a final check I have been going through the datasheets of all these parts t
