Hello, we use an oven to dry our MSL components after the floor lifes expires. The oven works at 40°C / 0.1% RH. The plan is to upgrade the oven from 40°C to 60°C to shorten the duration of the process. I have found a number of articles mentioning

For instance, do you require recognizability, booking, materials acquiring and taking care of, accounts, Client the board programming, BOM and ECN Control and so on. Do you have frameworks on the shop floor that handle a portion of the abovemention

Hi Jeff, Good question, but entirely dependant on what you are trying to do with it, your budget, and your company's eco system. For example, do you need traceability, scheduling, materials purchasing and handling, accounts, Customer management sof

Hi all, I mean after post adhesive oven curing (SMD at bottom side) prior to manual insert of PTH components (top side), what is the recommended storage time prior to wave soldering in order to avoid pin/blow holes and sunken joints issues (pcb asse

It depends on the laminate but a PWB is like any other MSL component. Some fab shops are only waranting standard FR4 laminates for 45-60 days when processed at lead free temperatures. The best thing I can say is to try some weight gain/loss experim

Dear SM Rookies, Another acceptable test method is visual inspection. IPC-A-610 details what to look for with different contaminants, providing magnified pictures of the possible visual residues. With an existing cleaning process, magnification

Methusala was very old yet he is still talked about thousands of years later. In my perspective, age of a thread is not the issue. It is the careless resurrection of a non-active subject that causes waste of time and space that is the issue. I can
