Manufacturing background and corporate history of Leamax Enterprise

Established in December 1990 in Taiwan, Leamax Enterprise Co., Ltd. developed an integrated production facility situated in Sanxia District of New Taipei City.

The factory incorporates precision high-speed stamping presses for contact manufacturing, modern injection molding equipment processing engineering thermoplastics, and semi-automated assembly systems.

Extensive tooling design experience enables the company to maintain rigid pin pitch geometry and dependable contact retention forces.

The complete connector portfolio aligns with the European RoHS directive and undergoes rigorous factory evaluations for mechanical vibration endurance, dielectric strength, and contact resistance stability.

Design features and technical merits of series 2120 IC sockets

Integrated circuit sockets series 2120-XXXE and 2122-XXXE are engineered to provide secure terminal connection for microprocessors and logic integrated circuits without thermal exposure during direct soldering.

Molded socket bodies utilize high-temperature PBT reinforced with 30% glass fiber, maintaining structural stability throughout thermal soldering cycles.

Contact terminals fabricated from phosphor bronze feature stamped or precision machined gripping clips that deliver contact resistance below 30 mOhm.

Terminal pitch spacing of 2.54 mm and 1.778 mm ensures reliable retention of semiconductor packages ranging from 6 to 64 pins under continuous operational vibration.

Application scope of series 2110 PLCC sockets for DIP and SMT layouts

To accommodate semiconductor chips in PLCC packages with rolled J-lead pins, Leamax Enterprise manufactures series 2110 sockets for through-hole DIP mounting and series 2111 for surface-mount SMT assembly.

Insulating housings molded from PPS polyphenylene sulfide and PBT with 40% glass fiber easily endure intensive reflow heating profiles.

Standard 1.27 mm contact pitch delivers balanced spring retention against every chip terminal, mitigating oxidation risks across electrical interfaces.

Molded corner extraction slots allow technicians to extract integrated circuits smoothly with extraction tools without inflicting mechanical strain on surrounding circuit traces.

Industrial D-SUB interface connectors series 3220, 3222, and 3224

The Leamax Enterprise D-SUB connector family spans cable solder cup types 3220, straight PCB through-hole types 3222, right-angle board units 3223, and compact high-density configurations 3224.
