Types of Assembly Services

We source all components, assemble the bare PCBs, test them if requested, and deliver assembled printed circuit boards.

Advantages:
  • Single point of responsibility
  • Simplify supply chain management
  • Shorter lead times
  • Enhanced quality and consistency
  • Simplified project management

Customer supplies all components, including the bare PCBs, and we deliver fully assembled printed circuit boards. We typically provide the necessary tooling, such as SMT stencils and fixtures since we have in-house manufacturing capabilities.

Advantages:
  • Customer retains complete control of component quality
  • Reduced component costs
  • Lower risk of obsolescence

The customer supplies some components; we source the rest.

Advantages:
  • Customer retains control over critical components.
  • Leverage manufacturer bulk sourcing for standard components.
  • Reduced project complexity as customer only needs to manage key components.
  • Faster time-to-production than full consignment by sharing sourcing responsibilities.

Our Full Range of Assembly Technologies

Our capabilities include precision automated SMT equipment for fine-pitch components such as BGAs, µBGAs, QFNs,
LGAs and advanced microprocessors; certified soldering technicians supported by wave and selective soldering
equipment; and mixed-technology assembly with both SMT and through-hole components on the same board.
Surface Mount Technology Assembly
Uses automated stencil printers, pick-and-place machines, and reflow ovens to build highly density boards with fine-pitch components.
Through-Hole (THT) Assembly
Uses a combination of hand soldering and automated selective and wave soldering equipment.
Mixed-Technology Assembly
Combines surface-mount and through-hole components for boards with large and fine-pitch electronic components.
Single-Sided and Double-Sided SMT Placemen
We offer full support for simple single-sided boards as well as high density, complex double-sided assemblies.
Lead-Free / RoHS Assembly
All materials including printed circuit boards, electronic components and solder paste as well as all processes comply with RoHS standards.
BGA / Micro-BGA Assembly
Requires X-ray to inspect hidden solder joints.
Flex and Rigid-Flex PCB Assembly
Sometimes it requires custom fixtures to support bends and folds.

SMT Assembly Process Overview

We designed our SMT assembly process to deliver precise, consistent, and high-quality results.

1. Fabricate SMT Stencils:
High-precision stencils made in house with LPKF micro lasers and fine-grain stainless steel.
2. Solder Paste Printing:
Apply solder paste to PCB pads using automated high-precision Yamaha stencil printers. Automated printing ensures accurate paste volume, alignment, and repeatability for defect-free solder joints.
3. Component Placement:
Automated Mycronic and Yamaha pick-and-place machines are used to precisely place SMT components on the boards.
4. Reflow Soldering:
Boards go through our automated BTU reflow ovens with controlled thermal profiles. The solder paste reflows (melts) and solidifies to create strong, reliable electrical connections.
5. Inspection and Quality Control:
Automated Optical Inspection (AOI) are used to detect misaligned, missing, or defective components. X-ray machines are used to inspect hidden solder joints, particularly on BGAs and micro-BGAs. Visual Inspection is also done to confirm placement, solder quality, and board integrity.
6. Rework and Testing (if required):
Correct detected defects. Perform functional or in-circuit testing to verify that the assembly meets all specifications.
  • Component Insertion: Place through-hole components into pre-drilled PCB holes. Done manually or with automated insertion equipment depending on volume and complexity.

THT Assembly Process Overview

Through-hole Assembly Process Overview

We designed our through-hole assembly process for applications requiring mechanical strength and high reliability.

1. Through-hole Component Insertion
Through-hole components are inserted manually or with automated machines into pre-drilled holes on the printed circuit boards.
2. Through-hole Soldering
We use Includes wave soldering for high-volume boards, selective soldering for specific components or areas, and hand soldering for specialized or hard-to-reach parts.
3. Cleaning
Removes flux residues or other for long-term reliability.
4. Inspection
Verify solder joints and component placement through visual and automated inspection.

PCB Assembly Frequently Asked Questions (FAQs)

Please provide a complete set of Gerber files (including board outline layer and paste layers), BOM (Bill of Materials), pick-and-place file also known as centroid file or XY data, and assembly drawings. instructions for polarity/orientation, photos and/or samples are very helpful

Yes, we can supply all the components, you can provide your own, or a combination of both.

Yes, it’s best to provide extra parts to prevent delays.

Typical extra quantities (guidelines)

  • Passive components (resistors, capacitors): 5–10% extra
  • ICs and connectors: 1–3 extra pieces
  • Fine-pitch parts, BGAs, µBGAs: 2–5% extra

A few small parts may be lost or damaged during feeder setup.
Spare parts will be needed for replacement if defective components are found.
Component counts from suppliers are not always precise.

SMT components are soldered to pads on the surface of the board, while through-hole components have leads that are inserted into drilled holes on the boards and soldered on the opposite side.

Placing and soldering BGAs, µBGAs, QFNs, and other bottom-terminated components is standard practice for us.

Yes, we assemble printed circuit boards with SMT and through-hole components.

Lead times on board complexity, component availability, and order volume.
Typical turnaround is 1–5 days for prototype assembly and 7–15 days for short-run and production volume.

We offer AOI, X-ray inspection, functional testing, in-circuit testing (ICT), and flying-probe testing.

Our turnkey services include conformal coating, wire harness assembly, and final product assembly (box build).
