摘要

Dave Bernard (Dage) and I have been considering a possible method of measuring the standoff height of PoP devices after soldering and the possible detection of any variation in the assembly process. Obviously you still use existing optical criteria and with possible enhancements planned in IPC 610; the document may become more useful to staff faced with inspection of area array devices. Alternatively the PoP inspection posters are available from the SMTA, IPC, SMART Group and www.solderingstandards.com
