Top Products
Quick Turn PCB Prototype with 3-5 Working Days Lead Time, 3/3 mil Line Capability, and Gerber File Review
Quick Turn PCB Prototype (3–5 Working Days) Huayihai fabricates quick turn PCB prototypes in 3–5 working days for engineering teams that need real boards fast — without stepping down to a lower process standard. Prototypes run on the same 3/3 mil line capability, the same surface finish options, and ...
Precision BGA PCB Assembly with 0.25 mm Pitch, X-ray Inspection, and Nitrogen Reflow for High-Quality Solder Joints
Precision BGA PCB Assembly (0.25 mm Pitch) Huayihai provides BGA PCB assembly for packages with ball pitches down to 0.25 mm. Because BGA joints sit underneath the package, assembly quality depends on placement accuracy, a controlled reflow profile, and inspection that can actually see the joints — ...
Custom SMT PCB Assembly with 01005 Placement, ±0.025 mm Accuracy, and Nitrogen Reflow Soldering
Custom SMT PCB Assembly (01005 and Fine Pitch) Huayihai provides SMT PCB assembly for OEM customers, from prototype builds to stable volume production. Boards are assembled according to customer Gerber files, BOM, and technical specifications, with placement down to 01005 components and accuracy of ...
Low Volume PCB Assembly with 100% Electrical Testing, 3-5 Day Lead Time, and SMT/Through-Hole Assembly
Low Volume PCB Assembly (Small Batch Production) Huayihai provides low volume PCB assembly for pilot runs, first customer shipments, field trials, and ongoing small-batch production. Assemblies are manufactured according to customer Gerber files, BOM, and technical specifications. Assemblies are ...
Consignment PCB Assembly with Customer-Supplied Components, 100% Electrical Testing, and 3-5 Working Days Lead Time
Consignment PCB Assembly (Customer-Supplied Components) Huayihai provides consignment PCB assembly for customers who supply their own components. In a consignment assembly project, the customer manages component procurement while Huayihai handles PCB fabrication, incoming material verification, SMT ...
Custom Backdrilled Multilayer PCB with 2 to 64 Layers, 16:1 Aspect Ratio, and ±5% Impedance Tolerance
Custom Backdrill PCB (Stub Removal) Huayihai fabricates custom backdrilled PCBs for high-speed designs. Backdrilling removes the unused portion of a plated through-hole — the stub — after lamination, so backdrilling removes the unused portion of a plated through-hole after lamination, reducing the ...
Custom Embedded Component PCB with Embedded Resistors and Capacitors for 2 - 64 Layers and HDI up to 2+n+2
Custom Embedded Component PCB Huayihai fabricates custom PCBs with embedded passive components — resistors and capacitors laminated inside the board structure rather than mounted on the surface. Embedded components free outer-layer area for active devices, shorten interconnect paths, and improve ...
Custom High-Tg PCB with High-Tg Laminate Options, Up to 64 Layers, and Lead-Free Reflow Compatibility
Custom High-Tg PCB Huayihai fabricates custom high-Tg PCBs on high glass transition temperature laminates. A higher Tg raises the temperature at which the base material softens, which keeps the board dimensionally stable through lead-free reflow, thermal cycling, and elevated operating conditions. ...
