Pcb Wire Strain Relief

Suggest a bonding material strain relief ie.

Pcb wire strain relief. 19 i o wire guage 18 guage these wires are soldered through hole method on the card s edge connector. We offer a wide array of products with applications across many industries. From standard solutions to custom designs we offer reliable cost effective products for mechanical electrical digital analog miniature and harsh environment. Then at the edge press the cables between the pcb and a metal bar.

Strain on electrical cables has been around as long as humans have been channeling electricity for our own devious uses and electrical strain relief designs have been around nearly as long. I have never seen a turret or special fixture used on a commercial board other than detachable connectors. Hello all i would like some suggestions as to the best way to strain relief i o wires on the edge of a circuit board. Search our portfolio of pcb connector strain relief models products and select your specifications.

In many items i have disassembled the wires have been looped once or twice through holes in the pcb for strain relief and then soldered in the normal way to a through hole pad. All discrete wires are considered to be components with the same bending soldering and stress relief requirements seen for other discrete axial radial devices. A strain relief is used to provide a transition from flexible cable to a rigid connector or connection point. So if i could keep it all on one side of the board that problem would be gone and i don t think the more fragile pads will be a problem that is why i wanted some strain relief on the cable.

Today there are several common designs each with some pros and cons. In this case the strain relief securing of the cables will be onto the pcb not to a casing. A strain relief also commonly called a bend relief is important to the electrical and mechanical integrity and overall performance of a medical cable assembly. I wire everything up and it fires up perfect.

This strain relief epoxy can be controlled to be either rigid or flexible depending on the requirements of the final product. My wires keep breaking. A properly designed strain relief will prevent mechanical force applied to the exterior of a cable from being transferred to. See section 6 01 through hole soldering general requirements for common accept reject criteria.

It is important to note that when designing strain relief into your rigid flex pcb design that you refer to ipc 2223 section 5 2 9 for complete guidelines and limitations. The pcb will be encapsulated or just given a layer of conformal coating so there isn t any casing i m considering to run the cables to the edge of the board.
