Pogo pin tester

thingiverse

I was inspired by the PCB workstation project on https://www.thingiverse.com/thing:2318886 to make a precise test probe holder which uses pogo pins. The target was to test 0201 components so I needed precise, reliable and easy to get spring loaded contacts and pogo pins seem the best choice for this. You can get pogo pins from many places but I used Farnell ones: - receptacle for the pogo pin - http://uk.farnell.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=359&urlRequestType=Base&partNumber=9960260&storeId=10155 - spring loaded contact - http://uk.farnell.com/harwin/p25-0123/probe-pointed-2-54mm-pitch/dp/9960210 The M3 holding nut is square like this one https://www.amazon.com/Square-Nuts-M3-Pack-100/dp/B009TDVF80 The result is simple and reliable tester which allows quickly to access the test points, you can attach the base plate to the desk by using Blue Tack (https://www.ebay.com/itm/221964019019) or by tape. In case you need to access more test points - 5 pogo pins holder is also attached to the project. The vertical columns are tilted on angle to allow the pogo pins to access test points which stay closer than 2.54mm. Added also a protector sleeve - it covers the pogo pin when not used to prevent it from accidental bending or damaging.
