Shenzhen EMS PCB Manufacturer & Turnkey PCBA Factory

Shenzhen EMS PCB Manufacturer

Shenzhen Merrillchip Electronics provides PCB manufacturing, PCBA assembly and EMS services for electronic product companies, engineering teams and OEM customers.

The manufacturing service covers PCB fabrication, component sourcing, SMT and DIP assembly, testing and final box-build. Projects can start with prototypes and continue through small-batch and mass production. The company states that it has more than 15 years of PCB and EMS manufacturing experience.

PCB Manufacturing

The PCB manufacturing capability covers 1 to 32 layer boards, including HDI, rigid, flexible and metal-core PCB structures.

Supported materials include FR-4, High-TG FR-4, aluminum, Rogers and PTFE. Copper thickness ranges from 0.5oz to 6oz, with heavy copper options available for higher-current applications.

Surface finishes include ENIG, HASL, lead-free HASL, OSP and immersion silver or tin.

SMT and DIP PCB Assembly

The assembly service supports SMT, DIP/THT and mixed-technology production.

SMT capability includes 0201 components, BGA and QFN packages, while DIP/THT production supports through-hole insertion together with wave and selective soldering.

This allows boards containing fine-pitch ICs, connectors, power components and through-hole devices to be assembled within the same manufacturing workflow.

Turnkey Component Sourcing

The EMS service includes BOM analysis, component procurement and kitting.

Components can be sourced as part of the turnkey manufacturing process, with incoming inspection and traceability procedures used for purchased components. Customers can therefore send their BOM and PCB files without having to manage PCB fabrication, component purchasing and assembly separately.

DFM and Engineering Support

Engineering support is available before production through DFM and DFA review, schematic and PCB layout consultation, prototype bring-up and test development.

The purpose is to identify manufacturing issues early and help improve production yield, cost and time-to-market before a project enters larger production.

PCB Testing and Quality Control

Testing and inspection can include AOI, X-Ray, ICT, functional testing, flying probe and burn-in.

The quality system is ISO9001 certified, with production following IPC-A-600, IPC-6012 and IPC-A-610 requirements. The page also lists RoHS, UL and CE among the applicable quality and compliance certifications.

Prototype to Mass Production

The EMS service supports quick-turn prototypes, pilot runs, small-batch production and mass production.

The page lists quick-turn PCB prototypes at 24-72 hours, while PCBA production and volume manufacturing are scheduled according to project requirements and component availability.

Full Turnkey EMS Manufacturing

The turnkey service can combine:

• PCB fabrication

• BOM analysis

• Component sourcing

• SMT assembly

• DIP/THT assembly

• PCB inspection

• Electrical testing

• Functional testing

OEM and ODM PCB Manufacturing

OEM customers can provide Gerber files, BOMs, schematics and other production documentation for engineering review.

Merrillchip can then coordinate PCB fabrication, component procurement, SMT/DIP assembly and testing as part of the manufacturing process. The service is suitable for both established PCB designs and new electronic products moving from prototype to production.

Global EMS Manufacturing

The manufacturing service is intended for customers that need PCB and PCBA production without managing multiple suppliers for fabrication, component sourcing and assembly.

From engineering samples and pilot runs to larger production orders, the same EMS workflow can be used for PCB manufacturing, assembly, testing and final delivery.
