How To Do Mass Production Testing of Your Board?

[@mrmaherani7077]

Thanks for sharing your priceless info as I'm designing a test fixture for our company and I have to deal with these challenges you've mentioned.

Interesting interview.

hi Robert, thanks for the great vidoe, I guess it could be better to keep questions in the later stage of the video, so presenter can start his presentation in his predefined order.

Hello, mayby you can show how to replace damaged receptacle when is soldered to the pcb?

[@enochabban9454]

Can the presentation slides be shared? 😅

[@f33net]

A good system should test itself and provide all the detailed information. And with the modern number of PCB layers, it is not particularly reasonable to scatter control points all over the board - you can drag everything to the diagnostic socket. 🙂

[@BassheadMusicConnoisseur]

A *expensive* good system. If you're making a cheap product or simple product it may be unnecessary to introduce self diagnosis and many software bugs

Can the test points be automatically placed in the layout? How? On a large board with 500 test points, doing this manually might be too much. Cannot add 500 symbols into the schematic, so it would be layout-only. Then some kind of a tool is needed to place them in the layout, or a script or option inside the layout tool. Any comment about what tool or function can be used for auto TP placement?

[@mason2426]

You really do want the TP's in the schematic. Especially if you have 500. This will let you crossprobe the TP on the net of interest to the PCB design in order to find the TP.

I don’t add them to the schematic for simple boards (

1mm is too big. Not possible to use smaller TP ?

[@fixturfab]

The smallest we recommend is 0.8mm, and even 0.6mm test points can be used. When using smaller test points just make sure you take care in the tolerance stack up of the entire fixture design to ensure that the test probes can still reliably make contact.

[@wtfucrazy]

He said 0.8mm could work also. But 1mm is better.
