Are you capable of doing Class 3 products? Does the design, bare PCB board and assembly meet the requirements of Class 3?

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

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.

Base on the top picture condition, seems like the boards condition is a lot with solder splash or solder ball which is per IPC-610 is under reject (under 5.6.2)for class 3 product. While the picture 2 is showing those the solder resist is not melt pr

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

Can you pl let us know what was the ESD sensitivity level of your assembly? We are also using plastic stencil from last 3 years and not seeing any major diffficulties in our class-3 product.

What is the minimum solder mask thickness required for Class 3 products. We are insisting fabricator of the pcb shop to use only spray coated solder mask. The SM thickness on the epoxy is about 17 microns, In the center of the tracks are 8 microns an

Hi Davandran ... Butt leads are not intended for high mechanical strength applications. That's why butt leads are not allowed in Class 3 products. If you want to be sure that your butt leaded component stays on the board, just glue it after solderin
