Economical Wire Terminations from Zierick
Insulation-piercing crimp SMT terminal.
Mt.Kisco, NY — Zierick Manufacturing Corp. has introduced a new surface mount insulation piercing crimp terminal and the tools that quickly and easily terminate a wire to SMT PC boards. The new terminals reportedly reduce production costs, improve reliability, and enable faster processing speeds. This new method of termination combines the advantages of crimping, insulation piercing, and SMT. According to the company, this terminal creates a highly reliable and economical way to terminate wires. The system consists of a surface mount terminal and a terminating machine which feeds the wire into the connector and makes the termination.
While the new crimp terminal and the termination tools can be used whenever a wire needs to be permanently connected to an SMT board, their most popular utilization is for instances where the wire passes through the terminal and numerous serial connections are made to one single wire. A good example is channel block lettering, where a series of LEDs is attached to a pair of wires.
Compared to conventional methods, this new system is less expensive than a two-piece pin/socket connection or an IDC (insulation displacement connector) type of connection which provides strain relief. It is more cost-effective than soldering wires to a board by hand. By comparison, it also takes up very little area on the printed circuit board.
The terminal has a flat base and two sidewalls perpendicular to the base. Two insulation-piercing contact spikes protrude from the flat base. Between the contact spikes is a flat area to facilitate vacuum pick-up and terminal placement. There are two deep score lines near the transition area between the sidewall and the base of the terminal.
The new process begins with the terminal being placed on the SMT board together with the other required components. After the assembly goes through reflow, it is moved to the terminating machine which feeds the wire into the terminal and crimps the terminal walls over the wire. In the process, the insulation piercing spikes penetrate into the wire without the necessity of removing the insulation. The crimp not only facilitates the contact, but also provides excellent strain relief for the wire. The two score lines on the terminal wall ensure that no deformation is introduced near the edge of the solder fillets, thereby preventing cracking and peeling of the solder joint.
