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

We are looking to have some PCBs (bare and assembled) independently tested for cleanliness. Our mfg facility is in Malaysia. Can anyone recommend a test house capable of testing to IPC-6012, IPC-5701, etc.

Generally, a well-designed assembly should not require man-handling of the PCB to the point where it is deflecting like this. Is the housing too small? What kind of clearance do you have and is there anything you can do to alleviate the issue (clos

Sorry for stating this incorrectly. It should been: Bow & twist for bare boards and panels: IPC-A-610 Acceptability of Electronic Assemblies, 10.6: 1.5% for PTH only and 0.75% for SMT, acording to test method TM-650, method 2.4.22 IPC-6012, par. 3.

I am new to the board so be gentle with me. There are standards such as IPC-610 for PCB assembly, IPC-600 for bare boards, etc. Is there a "standard" for electro-mechanical assembly? Is there an IPC standard or any other industry approved standard

My software can easily open a PCB CSV file so this is probably the easiest way for you to generate a file. The setups are remembered via a write to the registry, so you can go with a standard set of values to arrive at a very usable file without havi
