Board vender for SMT Module

[thomasluck]

We need to create a PCB module that is then surface mount to another PCB and having troubles finding a vendor that can TAB route through a Pad to create the contact point. Any suggestions for PCB vendors?

Normally when my back is against the wall with a fabrication issue I depend on two very reliable sources:

Dynamic Details
Brian McDermott
Director of Technology
714.390.1700
Anaheim, CA

or

Hallmark Circuits
Rick Norfolk
Sales Applications Engineer
858.513.2200
Poway, CA
data@hallmarkcircuits.com

Let me know if either one of these contacts can help you. I need to know if my referral system is working.

Could you please explain what this means? I am curious. Do you want to use bond wire through a hole onto a tab?

I can understand the secondary board laying ontop of the other board, but how do you envision the connection? I am trying also to understand how a bare board fab house would fit into this.

After digging a little on this subject I have found some information. It is called castellated PCB. Basically your are tab routing through a plated through hole leaving about 1/2 of the barrel in the hole (which is not the easiest thing to do). By doing this this module can then be surface mounted on another board like a leadless carrier. A example of this is a linx RXM-XXX-LC-S receiver module at http://www.linxtechnologies.com/ldocs/pdfs/lcsreceivdg.pdf

We do have one board house that did this job but, it they are very expensive plus the clean up work to complete the module is time consuming.

I see, now it makes sense.
