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 data and PCB specifications
PCB 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

PCB fabrication can be coordinated with component sourcing and assembly as part of a turnkey manufacturing program.

Supported PCB technologies include:

Single-Sided PCB
Double-Sided PCB
Multi-Layer PCB
Rigid PCB
Rigid-Flex PCB
Heavy Copper PCB
High-Tg PCB
Controlled Impedance PCB

We review applicable PCB requirements including material, board thickness, copper weight, surface finish, stack-up, controlled impedance, drill specifications, and panelization before fabrication.

For turnkey projects, PCB fabrication can be coordinated together with component procurement and assembly.

SMT Assembly

Our SMT lines support prototype, NPI, pilot, and repeat production, including single- and double-sided PCB assemblies.

SMT capabilities include:

01005 Passive Components
Fine-Pitch ICs
BGA
QFN
LGA
CSP
Bottom-Terminated Components
Double-Sided SMT Assembly
Mixed Component Technologies

Typical SMT process:

Solder Paste Printing → SPI → Component Placement → Reflow → AOI → X-Ray where required

X-Ray inspection is used where required for BGA and other packages with hidden solder joints.

Through-Hole & Mixed Technology Assembly

Many industrial, power, communication, and control products combine SMT components with through-hole connectors, terminals, transformers, power components, and other mechanically loaded parts.

Our THT capabilities include:

Manual Assembly
Wave Soldering
Selective Soldering
Press-Fit Components
Connector Assembly
Terminal Assembly

For mixed-technology PCBAs, SMT and THT operations are planned as one manufacturing process.

Assembly sequence and soldering methods are reviewed based on the actual board layout, component requirements, and mechanical constraints.

Component Sourcing & BOM Management

For turnkey PCB assembly projects, we can manage component sourcing together with PCB fabrication and assembly.

Our sourcing review includes:

Manufacturer part number verification
Authorized and established supply channels
AVL / AML requirements
Component availability and lead time
Lifecycle, EOL and NRND status
MOQ / SPQ requirements
Alternate component options
Customer-specified sourcing restrictions
Material traceability where required

Customer-supplied and consigned components are also supported.

If a specified component is unavailable or approaching EOL, we can help identify possible alternatives for customer review.

We do not substitute design-sensitive components without customer approval.

Component Replacement Support

Component replacement is not always a simple BOM change.

When an alternate component is required, our engineering review may include:

Pinout and package compatibility
PCB footprint compatibility
Voltage and current ratings
Electrical characteristics
Thermal requirements
Surrounding circuitry
Communication interfaces
Mechanical constraints
Firmware impact where applicable

A part with the same package is not necessarily a drop-in replacement.

If a pin-to-pin replacement is not available, schematic or PCB layout changes may be required before the alternate component can be used.

Any design-sensitive substitution is reviewed with the customer before implementation.

Prototype, NPI & Production PCB Assembly

We support PCB assembly from engineering prototypes through NPI, pilot builds, and repeat production.

Prototype PCB Assembly

Prototype builds are reviewed using the same manufacturing data required for production, including BOM, Gerber files, Pick & Place data, assembly drawings, programming, and test requirements.

This helps identify component, assembly, and documentation issues before moving to larger production quantities.

NPI & Pilot Production

For NPI and pilot builds, we focus on:

BOM and revision verification
DFM / DFA review
Component sourcing and availability
Assembly process planning
Programming requirements
Inspection and test requirements
First Article Inspection where required
Manufacturing feedback before production release

Repeat Production

For repeat builds, controlled BOM, PCB, assembly, firmware, and test revisions are maintained to reduce production errors between manufacturing lots.

We support high-mix, low-to-medium volume PCB assembly as well as repeat production programs.

Inspection, Testing & Quality Control

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

Our inspection and test 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

For BGA, QFN and other packages with hidden solder joints, X-Ray inspection can be used to verify solder quality where required.

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

For new builds, test requirements should be defined before production whenever possible so that programming, fixture, connector, and test-point requirements can be reviewed in advance.

Test results and inspection records can be maintained according to the agreed production and quality requirements.

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

Manufacturing and inspection activities are performed according to applicable workmanship standards and customer-specific requirements.

Quality control also includes:

Component traceability
Document control
BOM revision control
PCB revision control
ECO / ECN management
Manufacturing work instructions
Inspection records
Customer-specific quality requirements

Equipment & Manufacturing Process

Modern equipment supports manufacturing capability, but consistent PCB assembly also depends on controlled processes, work instructions, trained operators, engineering oversight, and inspection.

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

Document & Revision Control

PCB assembly production depends on consistent and controlled manufacturing data.

For each production build, applicable revisions may include:

BOM
Gerber / PCB fabrication files
Pick & Place data
Assembly drawings
Firmware
Programming files
Test procedures and acceptance criteria

When a new revision is released, the affected manufacturing documents and requirements are reviewed before the next production build.

BOM, PCB, assembly, firmware, and test revisions should match the approved production configuration.

Box Build & Final Assembly

In addition to PCB assembly, we can support box build and final product assembly for applicable projects.

Services may include:

PCBA installation
Cable and wire harness assembly
Connector installation
Mechanical assembly
Enclosure integration
Firmware programming
Functional testing
Labeling
Final inspection
Packaging

This allows PCB assembly, testing, and final product integration to be coordinated within the same manufacturing program.
