Zig-zag sockets are used to interconnect integrated circuits and memory chips arranged in a staggered double row pattern to a printed circuit board. They contain precision-machined receptacles with multi-finger contact clips housed in thermoplastic insulators. Machined pin sockets use a brass shell housing a reliable beryllium copper contact clip to securely connect device leads. Zig-zag and machined pin sockets provide protection, easy replacement, and cost-effective connections suitable for industrial, medical, aerospace, consumer, automotive, and military applications.

1. ZIG-ZAG SOCKETS

2. ZIG-ZAG SOCKETS:
• Zig-Zag sockets are suitable for the protection of IC’s and
memory chips with staggered double row patterns.
• This type of sockets are used for mostly interconnecting IC’s
and memory chips to a printed circuit board which has a
plurality of contacts in two parallel and offset rows.
• Zig-Zag Sockets are assembled with precision-machined
receptacles with multi-finger contact clip and packaged in high
temperature thermoplastic insulators.

3. MACHINED PIN:
• Machined pin sockets are made with two-piece construction.
Shell or sleeve is made of brass alloy 360 ½ hard, an alloy
known for its strength, conductive, and thermal properties.
• Press-fit assembled inside each shell is a highly reliable,
four-finger beryllium copper contact clip, which scores the
mating device lead, forming a gas-tight electrical and
mechanical connection.
• Multi-finger contact clips are superior to stamped pin wiping
connector blades because they provide multiple points of
contact to the mating pin, resulting in providing better
power and force distribution.
• Two-piece receptacle construction (shell and contact clip)
allows for cost-efficient plating combinations. Receptacle
shells can be plated with tin for solderability. Contact clips

4. ADVANTAGES:
• Protects IC’s and memory chips from damage.
• Provides easy handling during replacement.
• Reduce Lead time while assembling on PCB.
• Cost-effective connection for industrial & commercial
environments.
• Good for rugged environments, industrial controls and other
critical applications.

5. APPLICATIONS:
• In medical equipment’s
• For aerospace applications
• In consumer electronics
• In automotive industries
• For military applications
