Common questions

PCB and PCBA questions

What files should I send for a quote?

For PCB fabrication, send Gerber files. For PCBA, include the BOM. Also state process, quantity, surface finish, target timing and application.

What are your lead times?

Multilayer prototypes within 48 hours, HDI boards within 96 hours. Batch lead times depend on the design and quantity.

Which materials and finishes do you support?

FR-4, high-frequency materials (Rogers, TUC, etc.) and rigid-flex. Finishes include ENIG, immersion tin/silver, HASL, ENEPIG and electroplated gold.

Can every design meet the listed maximum capability?

Not automatically. The capability figures are references; engineering confirms feasibility for the specific stack-up and design.

Inside the factory

Watch AJW PCB at work

A look inside our Shenzhen plant — from drilling and imaging to final inspection of high-precision boards.

Factory tourHigh-precision PCB production at our Shenzhen plant

A walk through our Shenzhen plant — from CNC drilling and laser imaging to lamination, AOI and final electrical test.

Take a virtual walk through our 5,000 m² Shenzhen facility. The tour follows a board from blank laminate through CNC drilling, laser direct imaging and plating, then into lamination, solder mask and surface finish. Every panel then passes automated optical inspection (AOI) and 100% electrical test before routing and final packing. It is the same repeatable process we run for prototypes and production alike, backed by 10+ years of engineering experience in high-end PCBs.

Board samples on our showroom shelves.

Our showroom shelves hold working samples of the boards we manufacture daily — high-multilayer, HDI, heavy-copper, gold-finger, castellated and high-frequency designs. Seeing a finished board up close is often the fastest way to judge surface finish, hole quality and registration. If you would like a sample pack for your next project, contact sales@ajwpcb.com.cn and we will arrange it.

Multilayer panels ready for delivery.

After routing, each panel is cleaned, edge-inspected and vacuum-packed before it leaves the plant. Finished boards are delivered in standard anti-static packaging with full documentation, so they arrive ready for your assembly line. We support small-to-medium batches as well as fast-turn prototypes, with real-time order tracking from lamination to dispatch.

Every board passes through automated optical and electrical inspection before it leaves our Shenzhen plant, so you receive the same repeatable quality on prototypes and production runs alike.

Multilayer PCB stack-up
Guide · Feb 2026

How to choose the right PCB laminate

FR-4, high-frequency and high-Tg materials explained — and how to pick the right one for your design, cost and reliability targets.

The laminate is the foundation of every PCB — it determines electrical performance, thermal stability and cost. Standard FR-4 suits most digital boards below 1 GHz and is the most economical choice. For RF, radar and 5G designs, choose low-loss high-frequency materials such as Rogers or Panasonic M6, which keep signal attenuation low at high frequencies. For automotive, industrial or power electronics that run hot, a high-Tg laminate (Tg 170 °C or above) resists delamination through repeated thermal cycling. When in doubt, send us your stack-up and operating conditions — our engineers will recommend a material that balances performance, reliability and budget.

HDI heavy copper PCB
Guide · Jan 2026

HDI vs. multilayer: which do you need?

A plain-language comparison of HDI and standard multilayer boards — blind/buried vias, density and when each makes sense.

Standard multilayer boards use through-hole vias that pass all the way through the stack, which consumes routing space on every layer. HDI (high-density interconnect) replaces them with blind and buried vias, laser-drilled microvias and fine line/space down to 50 µm, so more circuitry fits in a smaller area. Choose HDI when your design is space-constrained — wearables, smartphones, high-pin-count BGAs — or when signal integrity demands short, controlled paths. Choose conventional multilayer when cost is the priority and density is moderate. AJW supports both, up to 64 layers for high-multilayer and HDI to 40 layers.

Company update: expanding quick-turn capacity

Our latest production updates and how we keep 48-hour multilayer and 96-hour HDI turnarounds reliable at scale.

AJW has expanded its Shenzhen quick-turn line to keep 48-hour multilayer and 96-hour HDI turnarounds reliable even as volume grows. The expansion adds in-house drilling, laser imaging and automated optical inspection capacity, so prototypes ship without waiting on outside vendors. For engineering teams, this means faster iteration cycles: upload Gerber and BOM, get a 20-minute quotation, and track your order in real time from lamination to final electrical test. Contact sales@ajwpcb.com.cn to discuss your next fast-turn project.
