X-Ray Inspection

Hidden solder connections under Ball Grid Arrays (BGAs) and Quad-Flat No-leads (QFNs) are inspected using high-resolution X-ray imaging to verify void-free solder joints.

Smart Logistics

Our intelligent warehouse utilizes real-time ERP integration to track component batches, sensitivity levels (MSL), and shelf lives, preventing manufacturing delays.

Tailored Solutions for Demanding Sectors

Different sectors require different standards. We adapt our manufacturing processes, component selection guidelines, and testing protocols to fit each industry's specific compliance requirements.

Medical Devices

High-reliability assemblies for diagnostic equipment, patient monitors, and imaging systems. We maintain clean production areas and complete component traceability.

Automotive Systems

Building robust electronics capable of handling extreme temperatures, constant vibrations, and harsh environments. Ideal for ADAS, power management, and infotainment.

Industrial IoT

Smart sensor nodes, controller boards, and communication gateways designed for continuous operation in dusty, humid, or electrically noisy environments.

Telecom & Computing

High-speed data processing units, server motherboards, and RF transceivers optimized for high bandwidth, low latency, and efficient thermal dissipation.

Global Standards, Quality Management & Sustainable Manufacturing

Our manufacturing operations are built upon a foundation of comprehensive international standards. By integrating ISO 9001:2015 quality management systems, we maintain high standards across all departments, including customer support, engineering, and final delivery.

In addition to quality, we focus on environmental responsibility. Our alignment with EcoVadis sustainability ratings shows our commitment to corporate social responsibility, carbon footprint reduction, and ethical supply chain management. This dual focus ensures that our high-performance electronic solutions are produced in a sustainable and responsible manner.

Through a process of continuous improvement, we regularly upgrade our manufacturing equipment, refine our testing procedures, and train our technical staff to adapt to the changing needs of the electronics industry.

Our Multi-Level Quality Framework

  • IPC-A-610 Class 2 & 3 Compliance: We build assemblies according to international acceptability standards, ensuring performance in demanding environments.
  • ESD Protected Areas (EPA): Complete ESD monitoring throughout the storage, assembly, and testing phases prevents electrostatic damage to components.
  • Full Traceability: Laser-etched barcodes on each PCB link the assembly to its specific component batches, operator logs, and test data.
  • RoHS & Lead-Free Processing: Dedicated lead-free SMT lines prevent cross-contamination and ensure environmental compliance.

Our Precision PCBA Manufacturing Process

We use a structured, 6-step manufacturing workflow to transition your designs from initial engineering files to high-performance, fully tested electronic assemblies.

Step 01

DFM & Engineering Review

Before production begins, our engineers review your Gerber files, BOM, and schematics to identify potential manufacturing issues, footprint mismatches, or component obsolescence.

Step 02

Solder Paste Printing & SPI

High-precision solder paste printers apply paste through laser-cut stencils. Our 3D Solder Paste Inspection (SPI) system verifies the volume, height, and alignment of the paste.

Step 03

Component Placement

Automated pick-and-place machines mount components onto the PCBs. High-resolution optical cameras verify the alignment of components prior to placement.

Step 04

Reflow & Wave Soldering

Boards pass through multi-zone reflow ovens with tailored thermal profiles to form reliable solder joints. Through-hole components are soldered using wave or selective soldering.

Step 05

Optical & X-Ray Inspection

Assembled boards are inspected using Automated Optical Inspection (AOI). For BGA and leadless components, we perform X-ray inspection to check for hidden voids or bridges.

Step 06

Functional Testing (FCT)

We perform customized functional testing to verify that the completed board meets the design specifications and operates correctly under load.
