Jiankun's production process adheres to professional quality control standards for electronics manufacturing and is divided into three core stages: front-end manufacturing, mid-end manufacturing and quality control, and back-end warehousing and delivery, as detailed below:
 

Front-end Process: Component Forming
1. Terminal Stamping and Forming
Using high-purity copper strip as raw material, high-speed precision stamping equipment is employed to cold-form terminal blanks. The structural precision and mechanical strength of the terminals are strictly controlled, laying the foundation for subsequent electrical connection performance.
2. Terminal Electroplating
Surface treatments such as gold plating, tin plating and nickel plating are carried out by qualified external suppliers. This enhances the terminals' conductivity, oxidation resistance and insertion/withdrawal durability, whilst meeting industry environmental and reliability requirements such as RoHS and REACH.
3. Injection Moulding of Plastic Housings
Engineering plastic pellets (such as PA66 and LCP) are melted at high temperature using precision injection moulding machines and injected into moulds to form the connector housing, ensuring dimensional stability, insulation performance and temperature resistance.
 

Mid-stage Processes and Quality Control
1. Automated Assembly
High-speed insertion equipment is used to precisely insert and lock the electroplated terminals into the injection-moulded housing, thereby forming the connector's electrical connection structure. The entire process is monitored by a vision positioning system to ensure assembly accuracy.
2. CCD Visual Inspection
A high-resolution CCD vision inspection system is utilised to perform automated inspection and yield screening for connector cosmetic defects (such as terminal deformation or flash on the plastic housing) and dimensional accuracy (such as terminal alignment deviation), with a detection accuracy of up to ±0.01 mm.
3. Tape and Reel Packaging
Qualified products are packaged using carrier tape and cover tape to meet the SMT automated placement process requirements of downstream customers, whilst preventing damage during transport and storage.
4. Final 100% Inspection
Through a combined 'manual visual inspection + electrical performance testing' process, we verify core electrical parameters of the connectors, including electrical continuity, withstand voltage and insulation resistance, to ensure products comply with industry quality system requirements such as IATF 16949.
 

Back-end Warehousing and Delivery
1. Batch-based Inbound Management
Qualified products are scanned into stock via the WMS (Warehouse Management System), enabling production batch traceability, real-time inventory control and First-In, First-Out (FIFO) management.
2. Order Fulfilment and Dispatch
