Hi Scott,Thank you for the response. I was also thinking the same that the assembly will no longer be Class III. Thanks again.

We have been using Cree 3 color LED's (CLV6A-FKB) in many products for several years (pic attached). At the rate of 3 to 5% of the units assembled with this LED, the Red LED fails. After touch up with soldering iron it functions. This happens to the

I've been tasked with finding out how difficult it would be to convert our company from a Class 2 to a Class 3 supplier. Does anybody know if there is a "how to" manual available to assist me in getting this done. Short of going thru all of IPC-A-610

Does anyone have any information or experience soldering of class 3 products with WS fluxes. We are currently leaning toward Alpha WS609 flux, however the customer's interpretation of J-Std-001C feels that type 'H' fluxes (WS) are not allowed. Any

WS609 is a wonderful paste. J-STD-001, 4.2 states words to the effect that for Class 3 products Type H or M fluxes should only be used for tinning operatins. Most water soluable fluxes are either H or M. I believe that you can use Type H or M flux

J-STD-001C, Table 11-1 is a good starting point.

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

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.
