Wire to board connectors solve the mechanical and electrical integrity problem of a reliable wired link, with features such as gold plated contacts, strain relief capabilities, and locking mechanisms that enable simple disconnection when required.So I will introduce you some features of wire to board connectors.

1,Shrinking wired connections
Connectors and cables promise a simple, reliable, and inexpensive solution for power and signal transfer between multiple printed circuit boards (PCBs) housed inside a single product. But to meet this promise, these connections must be robust enough to ensure high signal integrity performance even when subject to vibration, dirt, and heat. A proven solution comes from connector maker Molex, which has developed a system comprising receptacle terminals, receptacle housings, and headers.Because the connector systems take up little board area and feature a very low profile, (Figure 3), engineers can take advantage of reliable and inexpensive wire-to-board connectivity in products that were previously too small to accommodate the technology
2,Built for automated assembly
Wire-to-board systems can prove to be a challenge for manufacturers of high-volume products because conventional headers feature awkward profiles and typically employ through-hole connections to mount to the PC board.Such features make it impractical to use automatic placement equipment to assemble the connector on the board, forcing manufacturers to add a manual process to the line, slowing down production.Measuring the crimp height is a quick, non-destructive way to verify the mechanical compression of the crimp around the wire’s conductor. The crimp height is defined as the distance measured from the top surface of the formed crimp to the bottom radial surface. A further visual indication of the crimp’s quality is the extrusions (or small flares) that form on the bottom of the conductor crimp resulting from the clearance between the punch and anvil tooling. If the anvil is worn or if the terminal is over-crimped, excessive extrusion results. Uneven extrusion may also occur if the punch and anvil are misaligned or if the feed adjustment is incorrect.
It is also important that the crimped receptacle terminal is mechanically aligned after assembly; misalignment of the crimped section and mating section by twisting or bending will make it impossible to insert the socket connector into the connector header.
3,Multifunctional application and favorable price
These connectors reportedly deliver simple, robust, repeatable and cost-effective wire terminations. They are designed to replace both labor-intensive and inconsistent hand-soldered connections, as well as costly, two-piece connectors in perpendicular, low-pin-count industrial, commercial, smart grid, and SSL applications with limited PCB space. They also overcome conditions that make it difficult to achieve repetitive and reliable processes and maintain solder integrity.Specific applications that are especially well-suited to benefit from the price and performance value that connectors offer include: industrial machine controls, power supplies, motors, drives, solenoids, sensors, fans, and pumps; commercial building controls, such as security and fire sensors; smart grid meters, breakers, and panels; and SSL applications, including: LED drivers, fixtures, signage and streetlights.
Wire-to-board connectors have more features in life. Many features require you to use them,you will find that your quality of life and device connection save you a lot of energy.
