I have a new customer that has a print calling for 2oz. copper finish for top and bottom layers, and 1oz. copper finish for the inner 6 layers. Now, they also have a stack up depicting each layer and thickness. It shows the outer layers of copper b

I saw a question regarding the acceptability of stacking chip components at this forum posted in 2000. Unfortunately no one could cite any applicable IPC sections at that time. I am now able to find that this is acceptable per IPC-A-610D, Section 8.

Busko I could not find anything related to chip stacking in IPC-7711. I guess you meant that some changes will be coming. Probably , a task group is working on that. Can you fax or e-mail that info so that I can have access to that info ? I will ap

You can refer to ANSI/J-STD-001B section 6.4.3.1 which states: "When part stacking is permitted by the assembly drawing(s)/ documentation, parts SHALL not violate minimum electrical spacing between other parts or components such as terminals or othe

Hi, We have recently been tasked with producing a PCB assembly that requires a chip resistor to be stacked on top of a chip capacitor (both are 0603 package size). This becoming a more common practice, I was wondering if anyone has been successful i
