Ideally, shelf life should be twelve months from application, but not all OSP's are the same so check manufacturer's instructions

Although we do not have any soldering issues with our OSP PCB's, I am trying to establish clear rules with regards pcb storage and shelf life. Our PCB's are supplied in metalised moisture barrier bags but without desicant, our current rules as follow

That is a lot of Mydata lines to place billions of parts.

Hi all, What the largest part I can place with these machines? I'm going to try to install a PLCC68 using the front light because the part is bigger than the backdisk and I want to make sure it can handle it. The part is about 30mmx30mm. Thanks

We are Currently running a Board and it seems that the SOT-223's on the bottom side have flux and water trapped under the part. Nothing has changed in our process and this is the only board that it is happening on. We are using Kester R562 water wa

If I am putting chip capacitors on a .063 FR4 board, what size package should we stay away from to avoid cracking? If I use 2 mil copper on the outside layers of a PCB, am I limited to what pitch of parts I can use? Specifically, will using 0603

How large of chip capacitor can we use reliably? I��ve heard they tend to crack. I��ve also heard if you pre heat the larger chip caps (1812 and above) before vapor phase reflow, they won��t crack. If I use 2 mil copper for a power supply board, a
