The function of jumper PLC connector

Table of Contents

In PCB design, sometimes we will encounter some boards with single-sided design, that is, the usual single-sided boards (there are many LED-type light boards designed). In such boards, only one-sided wiring can be used, so we have to use Jumpers Of course, in complex boards, the problems that can be solved with jumpers are basically not problems.

1. Requirements for setting jumpers
a. The type of component to be set as jumper.
b. Jumper IDs are set to the same non-zero value for both pads in the jumper wire assembly. Note: Once the component type and pad jump properties are set, the component behaves as a jumper.

2. How to use jumpers
After doing the above steps, at this stage, there is no automatic network inheritance; after placing a jumper in the work area, you need to manually set the net property of one of the pads in the pad dialog. Note: If the component is defined as a jumper, another pad will automatically inherit the same net name.

3. Jumper display
In later versions of AD, the View menu includes a new Jumper submenu that allows control over the display of jumper components. And a submenu has been added to the netlist popup menu (n shortcut), including options for controlling the display of jumper connection lines. Note: A new query keyword, Is Jumper Component, has been added for filtering and rule definitions.

4. Create a jumper schematic in the PCB library
First a footprint is created, typically, jumpers are designed in pre-defined lengths, such as in 0.1 inch (100 ms) increments. As mentioned before, there are two conditions that need to be met: 1. Both pads in the jumper must have the jumper ID set to the same, non-zero value. NOTE: Do all the jumper schematics used in the motherboard design have the same jumper ID value for the pads. 2. The jumper part must have its type set to jumper. This option can only be set after placing the Footprint in the PCB workspace, it cannot be set in the PCB Library Editor.

5. Create Schematic Jumper Components
a. Create a single jumper assembly, then add all the different lengths of jumper you need to the schematic. b. Create a separate jumper assembly for each different length of jumper.

6. The location and use of jumpers on the PCB
After completing step five, when Design » Update PCB, all jumpers will be placed into the PCB workspace using the default footprint to show the right side of the board shape; the image below shows an almost fully routed pcb, note the remaining The connecting lines show where the wiring is not complete.
The board is basically connected, and some connections can’t be made because there are no paths available in this one-sided design. To complete them, jumper assemblies will be used.
