Why HIFAM pins

Consistent pins
for automated lines

A pin that is a few microns off can jam an insertion machine, weaken a solder joint or raise contact resistance. HIFAM controls every step from copper wire to plating so each batch stays consistent.
Micron-level tolerance
Cross-section ±0.01 mm, length ±0.1 mm. Straight, square, burr-free pins.
Double-lock carrier
Tape pins use a patented two-point self-locking design, so pins stay on the carrier during soldering.
Automotive grade
Plants certified to IATF 16949 and ISO 9001. Fish-eye (press-fit) pins certified to IEC 60352-5.
Selected copper
Copper from leading Chinese mills plus imported material from Germany, the USA and Japan. High conductivity and corrosion resistance.
Full-process inspection
In-house lab tests dimensions, hardness, resistance and reliability from sample to shipment.
Made to your drawing
Cross-section, length, pitch, bend shape, material and plating are all customizable.

FAQ

Questions about PIN pins

What is a PIN pin and what is it used for?

A PIN pin (contact pin) is a metal part, usually copper or copper alloy with plating, that conducts current, connects circuits and carries signals in connectors, relays, transformers, motors, power modules and other electronic devices.

Should I choose loose square pins or tape square pins?

Loose pins suit manual assembly, medium volumes or pins that need custom bends. Tape pins feed straight into automatic insertion machines, so they suit high-volume connector and header production. HIFAM tape pins come in 8 pitches from 1.27 to 3.81 mm.

What is a fish-eye (press-fit) pin?

A fish-eye pin has a compliant eye-shaped section that is pressed into a plated PCB hole to make an electrical and mechanical connection without soldering. HIFAM fish-eye pins are certified to IEC 60352-5, the standard for solderless press-in connections.

Tin plating or gold plating?

Tin plating is low-cost and solders well, suiting most connectors and PCBs. Gold plating gives low contact resistance and strong oxidation resistance for low-level signals, frequent mating or harsh environments. PROSTECH recommends plating based on your application.

Can you make pins to my own drawing?

Yes. Cross-section, length, pitch, bend shape, material and plating are all made to drawing. Send your drawing to PROSTECH through the form below for a quotation.
