Optical Inspection Equipment for PBGA | 2 January, 2002

Hello All,

Hope you had great holidays and are all rested up for 2002!

I would like some feedback on various optical inspection equipment for PBGA that different companies have used - the drawbacks to look out for, certain features that can be recommended..

I was at the Boston show last year and observed several models, so I have an understanding of what is involved, but would prefer to have some information from people that actually use the products.

Thanks in advance.....

Carol

Search the fine SMTnet Archives to get started. For instance http://www.smtnet.com//forums/index.cfm?fuseaction=view_thread&CFApp=1&Thread_ID=1815&#Message17271&

Key suppliers are: * Caltex "Hirox" scope at http://www.bgascope.com.

* ERSA Scope at http://www.ersa.de

The issues are: * Seeing what you want to see. => It's difficult to view more than four [maybe up to six] rows of balls deep. * Affording to replace the prisms in a production environment. * Justifying the purchase price [~$30k].
