PCB Assembly & Manufacturing Capabilities

Our Taiwan facility supports PCB assembly from engineering prototypes and NPI builds through repeat production.

Each project is reviewed based on the actual PCB, BOM, component technology, production quantity, programming, inspection, and testing requirements.

Engineering Review Before Quotation

A reliable PCB assembly quote starts with consistent manufacturing data.

Before quotation and material procurement, our engineering team reviews the available project files for issues that could affect PCB fabrication, component sourcing, assembly, testing, or delivery.

Typical review items include:

BOM completeness and manufacturer part numbers
Gerber files, PCB specifications and stack-up where applicable
Pick & Place data
Assembly drawings
Component polarity and orientation
Package and footprint consistency
Component availability and lifecycle status
Alternate component requirements
DFM / DFA / DFT considerations
Programming requirements
Functional test requirements
Special manufacturing processes

Common issues include BOM/Gerber revision mismatches, missing or incorrect part numbers, unclear component orientation, unavailable components, and incomplete test requirements.

If something does not match, we clarify it before materials are purchased or the assembly is released to production.

PCB Fabrication and Assembly

We coordinate PCB fabrication to customer-approved specifications and perform SMT, through-hole, and mixed-technology assembly in Taiwan.

Our assembly capabilities cover single- and double-sided boards, fine-pitch packages, BGA, QFN, LGA, CSP, and through-hole connectors and power components. Assembly methods and inspection requirements are reviewed for each build.

For detailed assembly capabilities and inspection methods, see our PCB Assembly Services.

Material Supply Options

We support turnkey, partial-turnkey, and consigned PCB assembly. Material purchasing responsibilities and approved sourcing requirements are confirmed before procurement.

All builds follow the approved BOM. Component substitutions require written customer approval before purchasing or use.

For PCB procurement, component sourcing, and BOM management, see our Turnkey PCB Assembly services.

Prototype and Production Support

We support engineering samples, pilot builds, and repeat PCB assembly orders.

For early-stage boards built for customer evaluation, see Prototype PCB Assembly.

For manufacturing preparation and pilot production, see NPI PCB Assembly.

For ongoing production planning and revision management, see our Electronics Manufacturing Services.

Inspection, Testing & Quality Control

Inspection and testing are planned according to the PCB assembly, component packages, production stage, and customer requirements.

Capabilities include:

Incoming Quality Control (IQC)
Solder Paste Inspection (SPI)
Automated Optical Inspection (AOI)
X-Ray Inspection
First Article Inspection (FAI)
In-Process Quality Control (IPQC)
Final Quality Control (FQC)
Outgoing Quality Control (OQC)
ICT where applicable
Functional Testing (FCT)
Power-On Testing
Firmware / MCU Programming
Customer-Supplied Test Fixtures and Procedures

Programming and functional testing can be integrated into production when firmware, test procedures, fixtures, and acceptance criteria are available.

For new builds, test requirements should preferably be defined before production so programming, fixtures, connectors, and test-point requirements can be reviewed in advance.

Quality Management & Certifications

Our manufacturing operations are supported by documented quality management and inspection processes.

Certifications include:

ISO 9001 — Quality Management System
ISO 14001 — Environmental Management System
ISO 13485 — Medical Device Quality Management System

Quality control includes component traceability, document control, BOM and PCB revision control, ECO/ECN management, manufacturing work instructions, inspection records, and customer-specific requirements.

Equipment & Manufacturing Process

Taiwan Manufacturing Facility

Our manufacturing equipment supports SMT, through-hole assembly, inspection, and testing across prototype, NPI, pilot, and repeat production programs.

Production is controlled through documented processes, work instructions, trained operators, engineering review and inspection.

→ View Equipment List

Document & Revision Control

Production follows the approved BOM, PCB, assembly, firmware, and test revisions. Changes affecting the build are reviewed before implementation. Required traceability and inspection records are agreed with the customer before production.

Box Build & Final Assembly

For products requiring assembly beyond the PCBA, we can install boards, cables, connectors, and supplied or approved modules into the enclosure, followed by the agreed programming, testing, labeling, and packaging.

See our Box Build Assembly services for assembly scope and quotation requirements.

Manufacturing Transfer to Taiwan

We support OEM customers transferring existing PCB assembly production to Taiwan or establishing a second manufacturing source.

For transfer projects, we review the existing BOM, PCB data, assembly documentation, programming files, test requirements, and current production revision before manufacturing release.
