With the help of this slide show one can understand what are Partially Filled Socket

1. PARTIALLY FILLED SOCKETS

2. PARTIALLY FILLED SOCKETS:
• Partially filled sockets are similar like DIP Sockets but with missing
pins in rows.
• According to the customers design and requirement some pins
are not assembled into the insulator to save cost and avoid
reworking.
• They can be used for relays.
• 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. For high-temperature applications of more than
150°C, an alternative beryllium nickel alloy is available.
• 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 can be gold-plated

4. ADVANTAGES:
• Protects IC’s and other PCB component 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
