The scope of our PCB Assembly Services

We offer SMT/SMD Surface Mount assembly to through hole assembly services for volumes from one off prototypes PCB assembly to short run projects or medium volume production quantities in our US assembly facility to speed up time-to-market for customers. When customer's volume grows higher, we help them to transfer the high volume production to our low cost China and Taiwan assembly facilities.

PCB Design and Layout

Our PCB design and layout partner is a well established world class PCB design house with more than 24 years of experience, with design centers in Northern California, Southern California, Taiwan and China. They deliver competitive solutions with superior quality and service.

PCB Fabrication

There is no single PCB fabricate house can meet all the requirements from every customer, that is why we have certified and established close partnership with more than dozen different types of PCB fabricate houses based on the different requirements of our customers, such as urgency of time, design complexity, volume and cost, etc. We will propose the best matching PCB fabricate house from local or overseas as appropriate:

  • Quick Turn Project– from local vendors capable of providing quick turn board fabricated, the quickest is within one day
  • Complex PCB Project –from PCB fabricate house can do higher-layer count PCBs and more complex assemblies
  • Price Sensitive Project – from price competitive fabricate house
  • Well Scheduled Project – for project with sufficient lead time, low cost PCB from overseas is available for all types of PCB requirements

Lead-free PCB Assembly

We offer leading edge lead-free PCB assembly (Pb-Free) and RoHS-compliant circuit board assemblies. We offer options for no-clean or water clean fluxes.

Leaded PCB Assembly

Although most of the customer use Lead-free process, but there are still some customers have to use Conventional Leaded Technology. Therefore we still support your PCB assembly with lead-based solder process. We offer options for no-clean or water clean fluxes.
Guide for a lead-free/RoHS compliant assembly can be found at Appendix 1 at the bottom of this page.

PCB Component Assembly Capabilities
01005 Component Placement & PoP (Package on Package)

We have full capability for assembling both SMT/SMD, Through-Hole and mixed technology PCB assemblies. Our surface mount PCB assembly capabilities include BGA, uBGA, 01005 component placements, PoP (Package on Package) and leadless devices assembly. We have accomplished a very challenging PoP (Package on Package) assembly with BGA down to 0.25 mm pitch.

3D X-ray (Ultra High Resolution) Inspection
for PCB Assembly / PCBA

PCB assembly, printed circuit board assembly, PCB circuit board Ball Grid Array (BGA) and Chip Scale Packages (CSP) are widely used in a PCB assembly. We use Nordson DAGE Ruby X-ray Inspection Systems to do ultra high resolution inspection for PCB assembly.

The Nordson DAGE XD7600NT is the perfect machine for the whole range of PCBA inspection tasks. This system is an ideal tool to help R&D engineers to do diagnosis for highly complex PCB assembly.

Appendix 1 - Guide for a lead-free/RoHS compliant PCB assembly:

  • Printed Circuit Board - Make sure to have your PCB vendor fabricates boards for lead-free / RoHS compliance. Make sure the PCB house uses materials that can withstand the additional heat and can make multiple passes through processing without problems.
  • Components: Your Bill-of-Materials must specify only RoHS compliant parts. The components in your kit must all meet lead-free and RoHS standards. The components must be able to withstand the higher temperatures required in manufacturing process. Even for RoHS compliant components, some of them cannot sustain high temperature. Please make sure to notify us if any component is heat sensitive.
  • Ball Grid Arrays: Ensure the solder balls of the BGA must is lead-free type. To solder a lead-based solder ball BGA at lead-free reflow temperatures will fail.
  • Moisture Sensitivity: Ensure components are kept in RoHS compliant storage packaging to prevent moisture. If any unopened package exceeds the expiration date or being opened, these components will need to be properly baked to remove the excess moisture.

Appendix 2 - Frequently Discussed Terms

  • Printed Circuit Board Assembly (PCBA): Printed circuit board assembly, also called as PCBA, is the process of soldering or assembly of electronic parts to a printed circuit board (PCB).
  • Surface Mount Technology (SMT) : Surface Mount Technology or SMT is a PCB assembly process for SMD electronic components. SMD components don’t have leads or legs. They are mounted on the surface of the circuit board. The equipments, electronic components and other soldering material used in this assembly process is different from thru-hole soldering process.
  • Through-Hole Technology (THT) : also called "thru-hole", it is the mounting scheme used for electronic components that involves the use of leads on the components that are inserted into holes drilled in printed circuit boards (PCB) and soldered to pads on the opposite side either by manual placement or by the use of SMD devices.
  • Ball grid array (BGA): A rectangular or square array of solder balls placed on one surface.
  • Surface-Mount Device (SMD) : An electronic device made for mounting or placing the electronics components directly onto the surface of printed circuit boards (PCBs).
  • Package on package (PoP) : This is a technology allows higher component density in devices, such as mobile devices. It is an integrated circuit packaging process to combine vertically discrete logic and memory ball grid array (BGA) packages. Two or more packages are stacked together, via a standard interface to route signals between each other.
  • Bill of Materials (BOM) : It is a list of the raw materials, parts , sub-assemblies, intermediate assemblies, sub-components and the quantities of each items to manufacture an the final product.


In summary, we offer PCBA, PCB /SMT/SMD assembly, PCB prototype assembly, PCB printed circuit board assembly and related services to OEM customers.
