MANUFACTURER INDEX
Compare what each company makes, where it operates and which sources support its profile.
Ji’an, Jiangxi
Welgao manufactures customised double-sided and multilayer PCBs, including thick-copper power, planar-transformer, Mini LED and optical-module circuits. The profile compares actual power and optical catalogue examples, batch/sample process rules and the distinct Huizhou, Jiangxi and Thailand manufacturing roles disclosed in the issuer’s 2025 annual report.
Hunan / Guangdong
Aoshikang manufactures circuit boards for automotive electronics, servers and storage, telecommunications and digital energy. Its technical offering includes backdrilling, controlled impedance, mixed-material construction and embedded features. Published support specifications cover high-layer fabrication, interlayer alignment and signal-loss test methods.
Shanghai
Shanghai Fast-PCB focuses on high-mix, small and medium batches and quick-turn PCB manufacturing in Jiading. Its original catalogue covers rigid-flex, RF/microwave and embedded-passive services. The profile separates copper-conditioned flexible rules, mass-production versus sample resistance limits and assembly-release requirements, with scoped UL and historical Shanghai primary records.
Shenzhen, Guangdong
Hitech Circuits provides PCB fabrication and assembly routes. Three original catalogue examples cover eight-layer Tg170 communication boards, ten-layer sequential HDI and six-layer three-ounce power boards. Buyers can define the bare-board stack, assembly partner/site handoff, functional-test coverage and the separate scopes of the UL holder record and Shenzhen PCBA certificate copy.
Shenzhen, Guangdong
Shenzhen Victory Electronic Technology Co., Ltd. provides varied PCB fabrication, small and medium batches and quick-turn services. Three individual catalogue examples cover six-ounce heavy copper, two-layer Rogers RO4350B and four-layer via-in-pad impedance control. Construction-specific source conflicts are retained for engineering clarification. The official Shenzhen site and scoped UL E315391 holder listing are cross-checked separately.
China
NextPCB provides PCB fabrication, flexible and rigid-flex services, component sourcing and assembly within the HQ manufacturing network. Its fourteen-layer HDI III example has construction-specific parameters; standard routing depends on copper and layer position. The HQ brochure separates Shenzhen prototype/small-batch production from Jiujiang mass production. UL and company-registry records are scoped to their named entities.
Shenzhen, Guangdong
PCBWay offers online PCB prototype and small-batch fabrication, advanced and rigid-flex boards, and assembly. Three individually sourced rigid-flex examples show different layer constructions, thickness and material requirements. Assembly turnaround starts after parts and manufacturing files are complete. Shenzhen government reporting documents the Jieduobang brand relationship; the official site names a separate Hong Kong global-service entity.
Shenzhen, Guangdong
JLCPCB provides online PCB fabrication, component sourcing and assembly. Its FR-4 routing rules depend on copper and layer construction; flexible and RF services have separate process tables. The HDI FAQ links microvia diameters to dielectric thickness. The group filing identifies JLCPCB as an online order channel and distinguishes the manufacturing network from support offices.
Huizhou, Guangdong
CEE manufactures multilayer, high-layer, HDI, FPC/FPCA and rigid-flex boards. Its named display-module, AR-glasses and sports-watch examples provide distinct flex structures and original construction parameters. The 2026 HLC roadmap separates sample from mass production; quotations should identify the nominated group plant and approved engineering revision.
Heshan, Guangdong
Olympic Circuit Technology manufactures double-sided, multilayer, HDI, flexible, rigid-flex and metal-base printed circuit boards. Automotive electronics is identified as its largest business area. Other application markets include industrial systems, computing, communications and medical equipment.
