Hello, I have a few PCB boards i am trying to be manufactured that are miniaturized medical devices. Thus they require IPC Class 3 Specs. However as miniature devices they have limited space, including a 0.4mm pitch BGA socket, which currently has

I think you needed an IPC Class 3 annular ring because for very dense designs, the smaller the annular ring the better, as less space is taken by the pad or via and more space can be dedicated to routing the traces in highly populated areas of the bo

You can't mix different Generation machines on the same base, but other than that, there shouldn't be any issue having different generation machines on the same line.

How about rework (touch-up) for Class 3? Some say that you are not allowed to rework anything for Class 3. Though I have not found any proof for this 'requirement' in the standards.

class 3 requires 100% barrel fill Class 3 requires 75% vertical fill of solder for component with less or more than 14 leads. Not 100% fill.

I can't say I've ever heard that you shouldn't rework class 3 products. Since class 3 and class 2 are inherently inspection standards, rework might be required to meet class 3 specs. In the past, that has been an issue, as everyone wants to produce

Rework is acceptable in class 3 but hardware defects shall be documented before rework and rework shall be documented.

Dear All, I'm just a budding engineer in EMS field. Here we used to manufacture different classes of PCBA. I would like to know about different process that need to be considered while manufacturing class 3 product. If we are going for microscopic
