PCB Jumper : a special component in PCBA process

PCB Jumper a special component in PCBA process

When the PCB design, a single panel and some complex boards had to use PCB jumper. PCB Jumper is actually a metal connection line connecting the two demand points of the printed circuit board (PCB), due to the different product designs, the jumper use materials, thickness are not the same. Most jumpers are used for the same potential voltage transmission, but also for the protection of the circuit reference voltage, for precision voltage requirements, a little bit of metal jumpers generated by the voltage drop will also make a big impact on product performance.

What is PCB Jumper?

A PCB jumper can be defined as a conductor which is adjusted or soldered between two points to make a connection. It basically acts as a bridge between two points. A PCB jumper is one of the important components of the motherboard, as it connects two points, and the connection of two points is necessary to work as a whole system. PCB jumper is used for various other purposes like adding layers of conductors, but the main purpose is making a connection between two points by joining them and providing a base for connection.
What is PCB Jumper and its types

What are the different types of jumper wires?

PCB jumper wires are simple wires and they have connected pins at both ends. The pins at both ends allow for the connection of two points. The pins at each end give the advantage of connecting without getting into the hassle of soldering. Breadboards are typically used with jumper wires or some other prototypes that give the freedom of changing the circuit without any difficulty.

There are three types of jumper wires that include male to male, male to female, and female to female. The difference among these types is that the male end has protruding and can be used to plug into things. On the other hand, the female end has no protruding and is only used to plug things into. One of the most common wires is male to male wire. For the connection of two points, this wire is mostly used.

What is the material of the PCB jumper?

PCB jumper plays an important role in the connection of remote electric circuits. The attachment of the jumper wire shortens the distance between the two circuits. PCB jumper is made from tin-plated copper wire. The material of PCB jumper wire can be single sided means one copper layer, it can be double layers having a double layer of copper on both sides, or it can be a multilayer means inner and outer layers of copper and added layers of substrate.

What is the use of a jumper in PCB?

In PCB, the jumper acts as an electrical design which is an opening and closing between two points. Depending upon the type of PCB, jumpers can also be added to the circuit board which can also change the default serial UART of the board. In computing, it is also known as the short length of the conductor. They are basically used to configure the printed circuit board.

What is the feature of a PCB jumper?

As we know that a jumper is also known as a short circuit bar. A PCB jumper is very similar to short-circuit plug, but a PCB jumper is mostly used in electronics including computer technology. Some of the features of PCB jumpers’ wires are that they are a few millimeters in size, and they come in the shape of a small socket. Inside the socket, there is a spring that connects the other pins. The housing of plastic serves the purpose of generating sufficient space and providing a shield against short circuits.

What is the difference between jumper wire and normal wire?

The normal wires are used in PCB jumper wires. Two points can be connected using the pins at both ends. The benefit of joining without the effort of soldering is provided by the pins at each end. Typically, breadboards are used in conjunction with jumper wires or other prototypes to enable easy circuit switching. However, the PCB jumper wires have some properties including:

● They are flexible braided wires.
● They come in multiple colors to help in color code porotype.
● There can be a length of your choice.

How do you solder jumper wires on PCB?

How do you solder jumper wires on PCBTo solder jumper wires on PCB is easier than you think. You just need to follow some steps and you are good to go with this whole process. First, you need to remove the dust or any other resistance from the repair area. You can use an alcohol cleaning swab, solvent cleaning pen, or some other method to remove extra dust. The next step is to apply flux to the existing traces using a soldering iron.

The next step involves the removal of the conductor. Next, strip and tin each end of the jumper wire. Now solder one end of the wire. You can adjust the wire as needed, and then secure the wire with the circuit of the board, and then solder the other end of the wire.

What kind of wire can I use for a PCB jumper?

Tin platter copper wire is mostly used for PCB jumpers. The material for PCB jumper wires can be single sided, which refers to having only one copper layer, double sided, which refers to having two copper layers, or multilayer, which refers to having both inner and outer layers of copper as well as additional layers of substrate.

What size is the PCB jumper wire?

What size is the PCB jumper wireThe typical size of PCB jumper wire is 0.1 mm which is 3.7g. Simple lines with connected pins at both ends are PCB jumper wires. Two points can be connected using the pins at both ends. The benefit of joining without the effort of soldering is provided by the pins at each end.


Jumper is an electronic component in PCB assembly for PCB cross-connection conductivity. PCB jumper design will affect the function and electrical connection of the PCB board, so it is also a problem that should be paid attention to in the PCBA.
