Sihui Fuji Electronics Technology Co., Ltd. manufactures multilayer and other PCB constructions from its Guangdong business, with a separately documented Thai production operation. Three original catalogue examples define different drawing reviews: a forty-layer S1190 test board, a forty-two-layer TU-933/HVLP4 backplane and a twenty-six-layer TU-872SLK stepped construction. Each retains its own photograph and parameters. Year-labelled process limits, the back-drill measurement definition and the backplane thickness discrepancy remain separate from order acceptance.
MANUFACTURING FOCUS- Thick multilayer test-equipment boards
- Back-drilled communications backplanes
- Depth-routed stepped interfaces

Haiying Electronics (四川海英电子科技有限公司) identifies its manufacturing site at 317 Mingxing Avenue in Suining, Sichuan. Its official catalogue separates FR-4, CEM-3, aluminium-base and higher-layer boards. The manufacturing documentation explicitly distinguishes Mass Production from Prototype, then supplies another processing table with different dimensions and hole definitions. This individually researched review keeps base-material choices apart from finished-board parameters, explains the sample-to-volume handoff, and connects the equipment disclosures with construction-specific release records. The original photographs are retained with their corresponding product entries. Government original-document retrieval remains incomplete, so no independent authority or certification conclusion is assigned.
MANUFACTURING FOCUS- FR-4 and CEM-3 material approval
- Aluminium-base thermal construction
- Mass Production versus Prototype transfer

Jiangsu Allfavor manufactures custom high-mix PCBs from its Nanjing base and related manufacturing entities. This profile reviews separately photographed six-layer Rogers, 6.0 mm high-frequency and 12 oz thick-copper entries. The technical page distinguishes sample, small-lot and large-lot rules and conditions routing on base copper. Dated issuer records help buyers assign the production site, subcontracting scope and construction-specific inspection plan.
MANUFACTURING FOCUS- High-frequency and high-speed PCBs
- Heavy copper and metal bases
- High-mix production

Chengzhiyi publishes metal-base thermal routes, copper inserts, thick-copper control circuits, blind/buried-via FR-4 and rigid-flex examples. Compare original board images, instance-specific data, thermal interfaces, electrical isolation and the separately identified Shenzhen, Dongguan and Jiangxi sites.
MANUFACTURING FOCUS- Anodised aluminium lighting boards
- Copper-base thermal circuits
- Copper inserts and thick copper
- Rigid-flex and blind/buried vias

Longteng Electronics (湖北龙腾电子科技股份有限公司) identifies Hubei Xiaochang and Zhuhai Longchang production bases. Its original catalogue documents an eight-layer robot HDI board, a mixed high-frequency/FR-4 construction and copper-base thermal entries. This profile keeps their parameters separate from the general and sample/volume process charts, with design-specific qualification and plant release requirements.
MANUFACTURING FOCUS- Prototype through volume production
- Communications and industrial PCBs
- Automotive circuit boards

Sun & Lynn Circuits manufactures rigid multilayers, HDI, flexible and rigid-flex circuits. Its original catalogue documents an eighteen-layer, four-millimetre power board with layer-specific copper, an eight-layer first-order HDI control module with immersion gold and OSP, and a four-layer wearable rigid-flex construction. These examples require different copper, finish-zone and mechanical release decisions. The official process tables separate standard from advanced routes; the advanced ±6% impedance entry is differential-only. Current site assignments distinguish Shenzhen, Ganzhou and Zhuhai factories from headquarters and business offices, while a dated Ganzhou government record provides an external entity/location cross-reference.
MANUFACTURING FOCUS- Thick-copper power circuits and plated-hole release
- HDI module finish zones and blind-via definition
- Wearable rigid-flex transitions and contour release

Gainbase manufactures single-sided and multilayer printed circuit boards at its Shenzhen factory, with a Hong Kong headquarters. Its published process range includes conventional rigid boards and 3+N+3 HDI constructions. The facility list includes laser drilling, LDI imaging, automated electrical testing and flying-probe testing. Its SMART service is directed at sampling, high-mix work and lower-volume requirements. The equipment list is a manufacturer disclosure, not an independent ownership or operating-condition audit.
MANUFACTURING FOCUS- Single-sided and multilayer PCBs
- 3+N+3 HDI
- High-mix, low-volume work
