PCB Assembly / Print Circuit Board Assembly
Flexible Cable Assembly Services
We specialize in quick-turn services for highly complexity and advanced PCB assembly and systems manufacturing in meeting your dynamic business needs.
Our competent engineering and manufacturing team help many customers resolve all kinds of PCB assembly problems which could not be fixed in other CM, thus we earned great reputation as the premier PCB assembly vendor. That is why many our customers refer many new customers to us. Our customers always find peace of mind when they send their PCB assembly jobs to us.
We offer 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.
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 most right match 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.
Example of our PCB Assembly Projects
(1) Very Large and Complex PCB Board Assembly:
- PCB board size = 18”x20”
- Component count > 7,500
- Flexible “film” of 5 mil thickness
- No fiducial designed on the film
- Placement of 0201-RP’s
- No stiffener at placement area
- Over 3,000 IOs
- 0.8mm vs. 47.5mm
- High weight of package
- We offer PCB assembly of single or multi-layer flexible or rigid circuit boards. The production areas are within an ESD and climate controlled environment.
- We have capability to manufacture very tiny flexible circuit board assembly as shown in the photo.
- We do through designs review before PCB assembly begins to avoid costly errors.
- Our quick-turn/rapid proto PCB assembly can be delivered as far as with 24 hours, which significantly help design engineers who needs rapid prototype PCB assembly.
- We are flexible for consignment or turnkey PCB assembly.
- Sparqtron was chosen primarily for it’s consistently and timely delivery quality PCB assembly.
- We offer superior service for providing immediate response to your most challenging PCB assembly requirements
- We build PCB assembly for defense, medical,communications, commercial and many other industries.
- We can handle 01005 SMT/SMD thick film chip resistors/capacitors placement and PoP (Package on Package) PCB assembly.
- SMT/SMD placement equipment(3 lines with 5 CPs, 01005 footprint, PoP)
- Screen printer
- Epoxy dispenser
- Reflow oven
- Wave soldering
- Cleaning system
- BGA rework station
- 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.

(3) High Density and Heavy BGA Assembly:
3D X-ray - Ultra High Resolution Inspection for PCB Assembly
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.
