Services

Everything between a schematic and a shipped product

Use one service or all three. Either way the same engineers follow your board through each stage.

PCBA solution development

Bring us a requirement, not just a Gerber. Our engineers take a product idea through hardware, firmware and validation.

  • Hardware design
  • Firmware development
  • Test and verification
  • Documentation

PCBA prototyping

Fast-turn prototypes built on the same lines and to the same standard as production, so what passes in the lab holds up at volume.

  • Design file review
  • Component sourcing
  • SMT assembly
  • Inspection and debug

PCBA manufacturing

Small-batch and volume assembly with full traceability, from bare board to tested, boxed product.

  • Turnkey or consigned materials
  • SMT placement
  • Through-hole (THT)
  • Burn-in and conformal coating
  • Box-build assembly

Process

Support across the whole product life cycle

Problems are cheapest to fix early, so each stage is designed to catch what the next one would otherwise pay for.

  1. 01

    Design

    We get involved early so the board is built to be manufactured.

    • Component selection support
    • DFX review (manufacture, assembly, test)
    • Process flow and PFMEA
    • Test strategy
  2. 02

    Prototype

    Quick builds with every issue recorded and fed back to design.

    • Fast-turn samples
    • Issue log and design feedback
    • New-process trials
    • Work instructions
  3. 03

    Pilot run (NPI)

    A controlled small batch proves the process before you commit to volume.

    • Process capability studies (Cmk / Cpk)
    • SPC and measurement system analysis
    • Failure analysis and corrective action
    • Process parameter sign-off
  4. 04

    Mass production

    Stable output, with cost and yield improved over the life of the product.

    • Volume purchasing savings
    • Capacity ramp
    • First-pass yield improvement
    • Digital delivery tracking

Quality

Tested, traceable and certified

Every board is inspected and tested before it leaves, and when something does fail we find out why.

In-circuit test (ICT)

In-circuit test (ICT)

Catches opens, shorts and wrong or missing parts on every board.

Functional test (FCT)

Functional test (FCT)

Powers the board and checks it does what the product needs.

Burn-in

Burn-in

Runs boards under load to surface early-life failures before shipping.

Fixture and test-plan design

Fixture and test-plan design

Custom fixtures and coverage plans built around your design.

Failure analysis

In-house analysis identifies the root cause and feeds the fix back into the process.

  • Component level
  • Assembly and soldering process

About

A manufacturing partner for the whole product life

Founded in 2015, JJ Factory (捷嘉智造) is a national high-tech enterprise building intelligent controller PCBAs for industrial, medical, new-energy automotive and smart-home products.

We run factories in Shenzhen, Dongguan and Suzhou. PCB design, prototyping, volume assembly and finished-product build are one service, with one team owning materials, production and test. That shortens time to market and reduces supply-chain risk.

Technology
High-speed SMT lines with solder paste inspection, in-line AOI, first-article testers and X-ray, run by engineers with 20 years of PCBA experience.
Quality
Checks at every stage from incoming materials to finished goods, under a certified quality management system.
Cost
An established supply chain, alternative-part proposals and one supplier for the whole build cut purchase, logistics and coordination cost.
Service
Engineering support from design through assembly, with regular follow-up after delivery.
