PCBWay vs JLCPCB: Compare Quotes, Capabilities and Engineering Requirements
Compare the same board specification, assembly package and delivery requirement before choosing a PCB supplier. This guide explains which differences to verify in an actual quotation.
What to compare first
PCBWay and JLCPCB both provide PCB manufacturing and assembly services. A useful comparison starts with your files and acceptance criteria. A promotional board price cannot establish which supplier is cheaper for a finished, delivered order.
This guide is published by AstroPCB, another PCB supplier. It is a procurement checklist based on the linked supplier information; it is not an independent factory audit or a side-by-side production test.
| Requirement | JLCPCB | PCBWay | What to verify |
|---|---|---|---|
| Board construction | Published PCB capability table | Published PCB capabilities | Your exact layer count, material, copper, thickness and finish must be available together. |
| HDI | Dedicated HDI service | Dedicated HDI service | Confirm the build-up, via spans, fill/cap process and approved stack-up for your files. |
| Assembly | PCB assembly service | PCB assembly service | Quote the same BOM revisions, approved alternates, sourcing plan and test scope. |
| Delivered cost | Obtain a configuration-specific quote | Obtain a configuration-specific quote | Include tooling, electrical test, assembly setup, components, freight and import charges. |

Compare complete quotes
Send both suppliers the same fabrication data, drawing, quantity and shipping destination. Fix the material grade or substitution policy, surface finish, finished copper and impedance targets before comparing prices. A quote using a different laminate or test scope is a different offer.
Separate board fabrication from assembly setup, component procurement and test charges. Check whether the price includes panelization, impedance coupons, reports and spare boards for assembly attrition. Compare fabrication lead time and transit time separately, including when the clock starts after engineering approval.
Keep a copy of each approved specification and quotation. For repeat orders, confirm whether engineering or tooling charges recur and how component shortages or substitutions are handled.
Check the complete construction
Do not classify either supplier as limited to standard prototypes: both publish HDI services. Check their current rules against the actual design rather than comparing one headline maximum. A minimum trace width does not mean the same feature is available with every copper weight, laminate or board thickness.
For HDI, submit a via schedule with start and stop layers, proposed build-up and filled/capped locations. For RF or high-speed boards, provide the exact laminate, foil preference, stack-up, impedance classes and channel requirements. For rigid-flex, provide bend zones, flex construction and assembly constraints.
AstroPCB’s own published planning values are 1–30 layers, 50/50 µm line/space, 0.10 mm mechanical drill, 75 µm laser drill with aspect ratio up to 1:1, up to 7 sequential laminations, 0.5–10 oz copper and ±8% controlled impedance. These are planning references; the combination is confirmed against the design.
Agree on evidence and acceptance
Ask each supplier which documents are included with your order: electrical-test results, impedance reports where specified, material traceability, inspection records and any requested microsections. Agree on acceptance criteria before production, including the treatment of deviations and rework.
If a program requires a particular certification or traceability package, confirm the certificate holder, manufacturing location, scope and applicability to the ordered process. A logo or general capability claim is not the same as an order-specific commitment.
When engineering review matters most
A written engineering exchange is useful when the stack-up is still open, the construction combines several demanding processes, or the acceptance package is unusually detailed. Ask who resolves DFM questions, which changes require your approval and how the approved construction is recorded.
The decision can still favor either online supplier if its confirmed process and support meet the requirement. If you want AstroPCB to evaluate the same package, use our DFM review and compare the returned scope, construction and delivery terms alongside the other offers.
Prepare the next build
Send the fabrication package for review.
Include the stack-up, material requirements, impedance table, quantity and required delivery date.
