| The myth of bow and twist testing |
In my trainings I feel that many times people are confused about the testing and acceptability levels of bow and twist as described in the various IPC documents.
Basically for the PCB manufacturer we find the information in the IPC-A-600 and IPC-6012 documents. The assembly department should take a look in the IPC-A-610 or IPC-J-STD-001. And the proper way of measuring is described in IPC-TM-650, test method 2.4.22.
For the PCB manufacturer the process is quite straightforward, perform some measurements (length, width or diagonal size and the deviation from the flat surface), and then calculate according to the above mentioned test method 2.4.22 to find the percentage of bow or twist and finally compare this value with the criteria from one of the above mentioned documents to see if it is a matter of scrap or deliver.
