Wire to Board Connectors by Scondar

Printed circuit boards placed inside electronic devices and system requires connection among substrates exterior portion when sending and receiving signal, and delivering power too. Generally, there are some distance among them which requires utilization of wired that will bridge the gaps. To achieve such long distance connection, you need to “solder the wire” to substrate. But for functionalities sake, it’s common for you to use multi-polar wire to board connector.

These wires to board connectors possess simple structures where the electrodes are situated in housing or case. There are 2 types of contacts and this includes receptacle and stick or plate like. The contacts need to be mated so that tab is tucked and wrapped on the device receptacle. In general, the said receptacle is being connected to tab and wire of the substrate, but this can be reversed according to usage. The contact and wire are almost connected utilizing the pressure bonding technique; this can be viewed in crimp style terminals; while pressure welding technique is utilized to connect wire and contact.

This type of technique is used for low current connection to enable across the board connected by mainly placing your covered wired in contacts. Regardless of the convenience, connection made utilizing the said technique can be compromised when it comes to durability. The mentioned 2 techniques prevent damages to connection as the result of heat which is inevitable during soldering. Furthermore, the gas tight connection areas does not have contact with air; making it likely to sustain reliable connection.

Choosing the Right Wire to Board Connection –The Guidelines

You might be wondering if the shape and number of wired is all the matters. The truth is, sum of the connecting wires and shapes needs to be your initial checkpoints whenever selecting connector. But it’s also essential to mull over the pressure and current in your circuit. To tell the truth, current of the circuit is the one that will indentify the wire diameter. This in return will verify if which connector is suitable to it. There are numerous kinds of contacts which are available in the market today. Availability commonly depends on wire diameter, it’s essential for your contacts to fit not mainly to the conductor’s diameter but with its cover as well.

When choosing contact plating, it’s necessary for you to understand the currents magnitude, pressure, and environment in which the said connector will be utilized. Specific pressure and current vary based on the connector’s type. Base on the “rule of thumb”, the highly dependable gold plating is utilized in low pressure, and low current connectors; while cost effective tin plating needs to be used in other connectors. Poles amount is another issue that you need to consider. Removing and inserting connector can establish unexpected high energy, since each contact create energy and higher energy is being create when more poles are available in the area. It’s possible to lessen contact pressure for each contact with gold platting but not with the tin plating. The tin plating necessitates relatively high-contact pressure which may lead to smaller-maximum pole amount than the gold plating.
