In a design where every bit of space and cost counts, replacing this programming connection with a group of exposed copper pads could make a significant difference. Tag-Connect has done an excellent job of developing a product that does just that: by replacing JTAG and other common programming connections with a small pattern of exposed, circular copper pads that interface with pogo pins (spring-loaded contacts that you can hold in place manually, or clip on if the connection supports it). There are other brands of cables that have built-in pogo pins but the general concept here is to convert bulky header-based connections to smaller, zero-profile connections that free up board space and cost.
Why is Pogo Pin PCB testing important?
It’s common to incorporate these on a test or debug PCB that might be utilized during a design or production process, typically if you want to run a functional test or probe a group of signals accessed by small exposed copper pads. These pads can be very close together and occupy minimum board space, a great way to save real estate in a space-conscious design. In order to better manage temporary, external connections by saving cost and board space, and creating a quicker, more reliable means to test or debug a PCB, consider adding pogo-pin-based connections to your design today.
How to use Pogo Pin connectors in PCBA?
Like most other components are Pogo Pins heat resistant only up to a certain point. Standard housing materials and spring materials may not be able to withstand the heat or can only go once through the reflow soldering process. If you plan to do several sessions, let us know! We will choose the right pins and the right materials for your requirements to avoid male function at a later stage.
What is the working principle of Pogo Pin PCB?
This article will look at:
- The basic structure of a spring-loaded connector
- Which kind of inner structure fits which application
- The electrical performance of pogo pins
- The durability of pogo pins
- The basic structure of a pogo pin.
A generic pogo pin consists of 3 parts: Barrel, Plunger, and Spring. Pogo pins are often inserted into housing for better stability, but in many cases, those pins are just soldered directly onto a PCB.
