Industrial Automation PCB & PCBA | Heavy Copper | NextPCB

Standard boards use 0.5, 1 and 2 oz copper, and 3 oz is also available. Inner-layer core copper is 0.5–4 oz, our online quote covers outer copper up to 6 oz and above, and the heavy copper process goes up to 10 oz. Minimum outer-layer trace and space is 3/3 mil at 1 oz, 5.5/5.5 mil at 2 oz and 8/8 mil at 3 oz. Send your copper weight, current and layer count so engineers can confirm the stack-up before you order.

High-Tg FR-4 with Tg 170 °C and above is available, including ShengYi High-Tg and KB TG170. We support thermal shock, high-temperature testing, T260/T288 delamination time, water absorption and insulation resistance tests, plus microsection analysis. For assembled boards, aging and temperature/humidity cycling are supported.

Yes. Conformal coating and potting are both supported. Our line cleans and dries boards before automated selective conformal coating with infrared curing, and our lab can test ionic contamination. Send the coating or potting type, thickness and keep-out areas with your assembly notes so engineers can confirm them before production.

ENIG is flat, hard and corrosion resistant, and it allows several soldering passes. Immersion silver can tarnish and has a shorter shelf life, and OSP has a short shelf life and does not suit repeated soldering. Hard gold suits connectors and edge fingers. Tell us the environment and we can recommend one.

Our online quote offers copper-base boards with 1–2 layers, 1, 2 or 3 W/mK thermal conductivity, 0.8–3.0 mm thickness, outer copper from 0.5 oz up to 6 oz and above, trace and space down to 4/4 mil, and HASL, lead-free HASL, ENIG or OSP finish. Aluminum, iron and stainless steel cores, copper coin and pedestal structures are also supported.

Flex sections can have 1–6 layers and rigid sections 2–32 layers, and we have built a 14-layer board with TG170 FR-4 and polyimide. Bend radius and cycle life depend on your design, so send your requirement for engineer review.

With no changes, engineering builds a repeat order from the files used for your previous order, including stack-up and impedance parameters. If engineers need to adjust your design, they contact you through an engineering question and start production only after you agree. Changes such as outline, drill, solder mask or thickness are noted on the reorder, and engineering updates the files and issues a change notice to planning. Samples and volume runs follow the same quality management system. For long-life parts, ask about our pre-purchase and storage service and run the HQDFM BOM check before you order.

Parts come through HQ Online, which connects to authorized distributors and manufacturers worldwide. Incoming parts are inspected, and X-ray inspection equipment is available. Date code and laser-mark traceability are supported, and our MES records production for traceability.

Yes. Firmware can be flashed from .hex, .bin and .elf files. Engineers and technicians debug the first article and turn your test plan into a work instruction before batch testing. Test fixtures can come from you or be built by us, and we support legally binding NDAs.

Prototypes ship as fast as 24 hours for 1–2 layers, 1–2 days for 4 layers and 2–3 days for 6 layers and above. Heavy copper, metal-core and rigid-flex timing is confirmed at quotation. Assembly is 24 hours for express and 5–7 working days with parts from HQ Online, and there is no minimum order, from 1 piece.

The main factors are board size and panel utilization (low utilization adds a surcharge), layer count, thickness, copper weight, surface finish (ENIG and plated gold cost more), drill size and hole density (holes under 0.3 mm add drilling cost), and special processes such as HDI, blind and buried vias, heavy copper, impedance control, half holes and edge plating. Engineering and test fees are included in prototype and small-batch pricing.

Final inspection covers dimensions, solderability, peel strength, microsection, thermal shock, ionic contamination and insulation resistance. Orders can include shipping reports, microsection reports and impedance test reports. Third-party RoHS, REACH (SVHC) and PFAS reports are available, and our UL file number is E469747 with UL 94V-0 flame rating. Defects found on delivery are repaired or reworked.
