—A one-stop integrated manufacturing solution from BOM assembly to complete system delivery
KINGBROTHER (Stock Code: 301041) leverages its IPDM (Integrated Product Design & Manufacturing) service system to build a vertically integrated capability covering "electronic engineering → PCB manufacturing → PCBA assembly → functional testing → complete system assembly → reliability verification". We offer more than just single-stage services; we provide truly turnkey PCBA services with the goal of successfully launching your products, comprehensively covering the following four key stages:
| Stages | Service Content | Core Capabilities |
|---|---|---|
| BOM Procurement | Customer BOM procurement, intelligent matching of multi-source alternatives, domestic material selection, material risk warning, collaborative management of customer-supplied and self-purchased materials, full lifecycle BOM cost optimization | • KBOM technology platform • 3.27 million+ certified materials library • Domestic alternative solution library (component localization rate up to 90%+) • Supply chain collaborative inventory mechanism (including chip shortage contingency plan) |
| PCBA Assembly | SMT (Supports 01005 ultra-small components, BGA/CSP/FPOP and other advanced packages), DIP through-hole mounting, double-sided mixed assembly, 3D assembly, conformal dispensing, flying probe testing, X-ray inspection, AOI/FAI/FCT full-process automated inspection | • Self-operated high-precision PCBA factory (20 SMT lines + 9 DIP lines) • Daily capacity of 17 million points (SMT) + 700,000 points (DIP) • Full process capability including lead-free reflow soldering (ten temperature zones), nitrogen reflow soldering, wave soldering, depaneling, programming, etc. |
| Functional Testing | Single-board FCT (functional circuit testing), system-level testing (SLT), communication protocol verification (USB/Ethernet/UART, etc.), customized automated test fixtures, test case development (including functional and reliability dimensions) | • Coverage of 1500+ testing items • CNAS/CMA Dual-Certification Laboratory (ISO/IEC 17025 Certification) • Supports environmental stress testing such as aging, temperature change, salt spray, and vibration |
| Final Product Integration | Multi-board interconnection assembly, precision assembly of boards and structural components, cable connection and wiring management, software pre-programming and firmware loading, label printing and compliant packaging, final product EMC/safety pre-inspection | • Micro-assembly lean production line (suitable for complex systems such as humanoid robots and surgical robots) • IPM (Integrated Product Manufacturing) platform • DFM/DFA pre-manufacturability analysis to ensure assembly feasibility |
Unlike traditional EMS manufacturers that focus solely on surface mount technology (SMT), KINGBROTHER uses IPDM as its methodology to break down the barriers between design (IPD) and manufacturing (IPM), achieving seamless collaboration across BOM, PCB, PCBA, EES (Electronic Engineering Services), and final assembly. This avoids delivery delays, blame-shifting, and quality fluctuations caused by fragmented processes.
