Hi, Do you know if there is any standard that specify that a component manufacturer shall mark a BGA component in the corner where you have the ball A1? Best Regards, Lars

Interesting. We are placing a camera that the marking is on the bottom..... No place to put it on top! The problem with the question is the word shall! I think the answer to the question is yes there is a standard but..... no law to enforce it....jus

Available on the web, JEDEC PUBLICATION 95, DESIGN GUIDE 4.14, Ball Grid Array Package (BGA), Figure 4.14-3, Note 10: A1 corner must be identified by chamfer, ink, mark, metalized markings, indentation or other feature of package body, lid or integra

We place these on a few boards and have no issues with reflow or warpage. How thick is your PCB?

when the cp6 loads a board everything seems normal / as the table drops the pcb lines up onto the origan hole and then instantly fails with -- "original pin error" we have run this board before. any ideas? thanks

The connector is so long, and has big metal parts, it will be little deformed during reflow I guess, andthe pins planarity should be critical for 200 pins. Did you measure the non wetting pins profile to see if temperature ok? And maybe you can try u

can anyone help with information about I-shape of SMDs. our Design includes this shape of contacts. we are searching for information on quality judgement of solder joints with I-leads on Pads. Please help.
