Finding Test Sockets for Magnetic Sensor SIP & MSOP Packages

Click For Summary

Discussion Overview

The discussion revolves around finding suitable test sockets for magnetic sensors packaged in SIP and MSOP formats, specifically for use in a quality control setting. Participants share various approaches and sources for obtaining these sockets, as well as considerations for their design and functionality.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant seeks assistance in identifying a proper test socket for SIP and MSOP packages.
  • Another participant suggests a specific website for MSOP test sockets but notes the high cost and mentions that many opt for making package adapters instead.
  • A participant shares a method of testing by designing a board with the package footprint, placing the chip directly on the pads, and expresses concern about ESD sensitivity.
  • Discussion includes recommendations for SIP sockets with 0.100" spacing that can fit into breadboards or female socket strips from manufacturers like Samtec or Mill-Max.
  • One participant specifies a need for a SIP socket with 0.050" spacing and expresses interest in test and burn-in type sockets.
  • Another participant admits unfamiliarity with test and burn-in sockets but suggests checking with the previously mentioned manufacturers.
  • A suggestion is made to contact Emulation Technology for assistance in finding the desired SIP socket.
  • One participant offers to help and requests private communication regarding requirements for a test socket.
  • A later reply notes that the original poster has not been active for over two years, which may limit responses.
  • Another participant recommends COMPOMAX Technology for test socket fabrication support.
  • A participant expresses a personal request for pointers on LIF or ZIF Single-In-Line socket strips.

Areas of Agreement / Disagreement

The discussion does not reach a consensus on specific test sockets, as participants share various suggestions and experiences without agreeing on a single solution. Multiple competing views and approaches remain present.

Contextual Notes

Some participants express uncertainty about the specific requirements for test and burn-in type sockets, and there are mentions of varying spacing requirements for SIP sockets. The discussion includes references to different manufacturers and sources, but no definitive solutions are established.

Who May Find This Useful

This discussion may be useful for engineers and technicians involved in quality control or testing of magnetic sensors, as well as those seeking information on socket options for SIP and MSOP packages.

i need to design a test equipment for magnetic sensors and i need to use this in quality control department. the magnetic sensors come in SIP and MSOP packages. i need a socket to hold both temporarily until the test is being carried out.
can anyone help me find out a proper test socket for these packages?

I Googled MSOP test socket, and here's a result that came up (kinda pricey though--most people just make package adapters, and not sockets):

If you only need to test one or two of something, and don't mind a slow throughput, what I've done in the past is to design a board with the footprint of the package, and then just put the chip down right on the pads and pressed down (not sure how sensitive your devices are to ESD, however). If you can't get them to line up well to the pads, you can always take them into place.

As for your SIP... If your SIP is 0.100" spacing, it should fit into a breadboard, or any 0.100" spacing female socket strip of the appropriate width. Try Samtec or Mill-Max. If you need more than just sample quantities, head to Digikey or Mouser (I believe both sell breakaway headers of various spacings made by 3M and the above-mentioned companies)

i need a SIP socket with 0.050" spacing. and it would be great if the socket is of test and burn-in type.

I'm not familiar with test and burn-in type sockets (ones that don't require any insertion force?) But you should be able to find something at the aforementioned manufacturers (and vendors). If you're looking for something really specialized, maybe someone else on this board can give you a referral.

You could try calling Emulation Technology. If they don't have it, they may be able to point you to another company that does. I've been very impressed with the customer service from ET.
 
hello humanoid... I would like to help. please email me your requirements if you are still in need of a test socket.. send me a private message...

Welcome to the PF. humanoid hasn't posted since this thread over 2 years ago, so you may not get a reply from him.

If you have a link to a good source of test sockets, go ahead and post it here.
 
Thanks Berkeman... For test socket fabrication support, they may try COMPOMAX Technology .. They could be of great help...
 
(selfish post by me) -- I'm looking for LIF or ZIF Single-In-Line socket strips. Do you have pointers that would help me out? Infraction for me...
