Methods and materials

How it is done.

The methods Indian factories run under electronics & assembly, and the materials they work in.

Methods

  • SMT assembly
  • Through-hole and wave soldering
  • Selective soldering
  • AOI and X-ray inspection
  • In-circuit and functional testing
  • Conformal coating
  • Box build and final assembly
  • Wire harness and cable assembly
  • Firmware loading

Materials

Typical MOQ
Often 500–1,000 boards per SMT run; prototypes of 10–50 boards are possible at a higher unit cost.

Buying tips

Buy it with confidence.

What experienced buyers put in the RFQ and check on arrival.

  • Share a complete BOM with approved alternates, because component availability drives lead time.
  • Agree test coverage (ICT, functional test) and who builds and owns the test jig.
  • Plan destination certification early: CE or UKCA for Europe and the UK, FCC and UL for the US, RCM for Australia and New Zealand.
Electronics & assembly questions

Is India a good place for PCB assembly?

Yes. India has a fast-growing EMS base in Noida, Chennai, Bengaluru and Hyderabad, supported by government incentive schemes. It suits high-mix, low to medium volume work as well as growing high-volume lines.

Can Indian EMS companies source components?

Most offer turnkey sourcing through authorised distributors, and many also accept consigned parts. Ask for traceability to authorised channels.

What standards do Indian EMS providers work to?

IPC-A-610 for assembly workmanship and IPC/WHMA-A-620 for harnesses are common. State the class (2 or 3) in your order.
