Turnkey PCB Fabrication & PCB Assembly Manufacturer in Shenzhen, China

PCB ADEPT is the export brand of Shenzhen ICSLOVE Technology, an electronics manufacturing partner that takes your project from bare board and component sourcing to tested, packed finished products.

Founded in 2020 in Shenzhen — China's "Silicon Valley" and home to Huawei, BYD and DJI — our engineering and production team brings more than 15 years of hands-on PCB and EMS experience. We serve industrial control, automotive, telecom, medical, aerospace, IoT and anti-drone customers, supporting fast prototypes, pilot runs and full-scale production under one quality system.

Production Capacity

6 SMT lines, 4 DIP lines and an 8,000 m² workshop, tracked end-to-end by a Manufacturing Execution System (MES).

Custom Engineering

Build-to-print manufacturing, DFM feedback, reverse engineering and product replication for legacy or end-of-life boards.

One Accountable Supply Chain

From Gerber Files to Delivered Product

Overseas buyers lose time and margin juggling separate board shops, assemblers and brokers. We consolidate the four critical stages under one contract, one project engineer and one traceable quality record.

STEP 01

Components & Custom Materials

BOM review, sourcing of TI, ADI, ST, Microchip, Murata and TE (Tyco) parts, alternates for long-lead items and shared stock of common components.

STEP 02

PCB Fabrication

Rigid, flex, rigid-flex, HDI and RF/microwave boards built to your stack-up, material and surface finish requirements.

STEP 03

PCB Assembly

SMT and through-hole assembly with SPI, AOI and 3D AOI inspection, with every lot recorded in MES for full traceability.

STEP 04

Box Build, Test & Delivery

Enclosure integration, firmware programming, functional testing, aging, labeling, packing and worldwide shipment.

Facility & Technology

Inside Our 8,000 m² SMT & DIP Facility

Select a station to see where it sits in the build flow and what it controls. Every stage below feeds data into our MES so each board can be traced back to its materials, operators and inspection results.

IQC incoming inspection of electronic components

Incoming Quality Control (IQC)

Components and bare boards are checked against the BOM and datasheets before kitting, so counterfeit, mislabeled or damaged parts never reach the line.

FAQ

PCB Assembly FAQs for Overseas Buyers

Straight answers to the questions procurement teams ask most before placing a first order with a Chinese PCBA manufacturer.

What is the minimum order quantity for prototype PCB assembly?

Prototype and trial-run PCB assembly starts from 1 piece and covers quantities up to around 500 pcs, with a typical lead time of 3–9 days depending on board complexity and component availability.

Which files do I need to send for a PCB assembly project?

Send Gerber files (or ODB++), a complete BOM with manufacturer part numbers, a pick-and-place (centroid) file and assembly drawings. Test instructions or firmware are needed if you require programming or functional testing.

How do you control PCBA quality?

Quality is controlled at every stage: IQC for incoming materials, SPI for solder paste, AOI before and after reflow, 3D AOI, first article inspection (FAI) and functional testing (FCT), all recorded in a Manufacturing Execution System (MES) under an ISO 9001 quality system.

Can you source components from brands like TI, ADI, ST and Microchip?

Yes. The sourcing team has over 10 years of experience procuring parts from brands such as TI, ADI, ST, Microchip, Murata and TE Connectivity (Tyco), and keeps an inventory of common components. Alternative parts are proposed when lead time or cost is a risk.

What certifications does PCB ADEPT hold?

Manufacturing operates under an ISO 9001 quality management system, and PCBs and assemblies can be produced to UL and RoHS (lead-free) requirements.

Do you offer box build and finished product assembly?

Yes. Beyond PCBA, the factory supports plastic enclosure molding, CNC machining, 3D printing, memory and MCU programming, finished product testing, aging, labeling, packaging and international delivery.
