Pogo Pins can be mounted via a cable on the PCB. The soldering pads should be "Radius of the Pogo Pin + 0.5mm". Only the tale of the pin should be "Thickness of FPC + 0.1mm" How to design the PCB for SMT mounted pogo pin connectors? How to design the FPC footprint for pogo pin connectors?įor Flex PCBs the rules are similar as for normal PCBs. These numbers may vary at smaller pitches and also depend on the tolerances your EMS is operating with. The tail itself should be at least "Thickness of PCB + 0.4mm" long. The soldering gold pad should generally be radius of the "flange + 0.4mm". How to design the PCB footprint for dip type pogo pin connectors?Īs a rule of thumb the hole in the PCB should have the radius of the "Pogo Pin Tail + 0.3mm". 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. Standard housing materials and spring materials may not be able to withstand the heat or can only go once through the reflow soldering process. Like most other components are Pogo Pins heat resistant only up to a certain point. What to pay attention to when using SMT with pogo pin connectors? We usually recommend this type of mounting when ever possible. This is a very secure way of mounting a connector and give the most stable and durable connection. This is a combination of Options 2 and 3 where the housing and the pins have plug-in tails. This version is generally stable enough for most applications. The third option is to use a housing with legs to mount the whole connector securely on the board while the pogo pins are simply mounted on a gold pad by pressure or solder paste (Option 1). The tail gives additional support to the pin and increases the stability. The second option is to use a pogo pin with a plug-in tail that is fixed by sticking the tail through a mounting hole on the PCB as it is common practice for most bigger components on the PCB. It generally isn’t very stable, and pins might break away or dislocated through vibration or the mating pressure. While this is certainly the easiest way, we usually do not recommend doing that. The first and most simple way is to place the connector on a solder pad and use solder paste to fix the connector in place. How to mount Connectors via SMT (Option 1-4) Besides your structure design, we will recommend a suitable way considering your product cost. Our engineers are true experts when it comes to all sorts of connectors and our long experience with over 6000 custom connector designs will be very valuable to avoid mistakes. If you have further questions after this article, please contact us directly. This article will go through all the different options, explains the advantages and disadvantages and gives some general advice. If you are looking into pogo pins for your application, you will sooner or later ask the question which mounting options are available for pogo pins.
