Onboard Plate: OGP-2520, OGP-3216, OGP-4520

OGP configuration ensures reliable contact.

  • OGP solves contact failure problems caused by solder flux
  • Better reliability compared with solder
  • Eliminates continuity failure caused by pattern scraping between a PCB and pogo pins and a PCB and a metal plate
  • OGP-2520 is 40 % or more downsized from OGP-4520. (Product size: 2.5 mm)
  • Gold-plated OGP-3216 can be used as a partial gold plating on PCBs

Resistance Measurement Results

Test method:

1: A terminal and OGP-2520s are soldered on a substrate. A second terminal is soldered on to a separate substrate, with solder fillets applied on the substrate at the same position as the OGP.
2: A screw is tightened in each location and the substrates are heat treated.
3: After the treatment, the resistance between the terminal and screw is measured with a Milliohm HiTester.
