Electronic Contract Manufacturing overview:


Our PCB assembly services include SMT assembly, mixed technology, and through-hole in a ESD protected, humidity controlled environment. Our high speed SMT lines are equipped with solder paste inspection, 40” high definition Inspection monitors with max magnification at 600X, 13 zone re-flow ovens and 3D AOI. Through-hole capabilities include an 18’ slide line with four high definition monitors, wave solder, or the use of the latest selective soldering technology equipment. PNC’s final inspection area includes (4) inspection stations with high definition monitors designed for employee ergonomic comfort.

Quantities range from small-number prototypes to large production orders. We serve the military/defense, medical, aerospace, automotive, industrial and consumer sectors. Since we have the capability to design and fabricate printed circuit boards in the same facility, we are able to turn concepts into prototypes in as little as 24 hours. Other PCB assembly services include functional testing, programming, conformal coating, 3D X-Ray, box builds, lead free and leaded rework stations.

The PNC Inc. quality system ensures that our employees are IPC-A-610 and IPC-J-STD Class III-qualified. Company certifications include, AS9100D, ISO 9001-2015, MIL-PRF-55110 and MIL-PRF-31032. Our SMT assembly area are ITAR-restricted per mil standards. We are ESD compliant to ANSI/ESD S20.20.


Surface Mount Technology (SMT)

We utilize state of the art Universal and Juki Pick & Place equipment in our SMT assembly division. These machines are capable of placing 17,100CPH to 23,500CPH with capacity to accommodate 160 8mm Electronic tape feeder with placement accuracy of +/-.05mm. Our Heller 13 zone re-flow ovens have 26 Independent temperature-controlled heating zones to accommodate the right profile whether the printed circuit board assembly is for double sided or multi-layer PCB’s.

  • Components as small as 0201 package size
  • Package types: QFPs, uBGAs, QFN, and BGAs
  • Two-sided assembly for Rigid, Flex and Rigi-Flex PCBs
  • Ability to do IPC-A-610 Class 1, 2 and 3
  • RoHS and Leaded assembly


PCB assembly services in the through-hole arena are many. Our expertise with Axial, Radial, DIP, Right Angle connectors, Header connectors, SIP sockets and pogo pins, to name a few that we work with daily. A majority of these components are soldered with the latest selective solder machine that is nitrogen assisted for hole fill consistency per IPC class standards. If the PCB assembly is 100% through-hole, we utilize an 18’ slide line equipped with 4 inline workstation high definition monitors to display each operators work tasks. This type of printed circuit board assembly would be passed through our wave soldering machine for mass production soldering.

  • Highly Skilled Staff IPC J-Std-001 trained and certified
  • Manual Through Hole Assembly
  • Custom Slide line for larger volume
  • Press fit connectors
  • Wave soldering
  • Select solder machine for Lead and Lead-free (RoHS) products


Most PCB assembly will require some type of through hole devices. Since this type of printed circuit board assembly has SMT components previously installed, the through-hole devices will be selectively soldered. Our ERSA selective soldering machine is nitrogen assisted to achieve the highest quality solder joints to meet IPC hole requirements.


Paste used in our SMT assembly lines is a no clean paste, but we clean 100% the PCBA’s providing there are no components on the printed circuit board assembly that cannot be aqueously cleaned, such as displays, switches, etc. Our Nano Jet Inline cleaning system is capable of both water and aqueous chemical cleaning applications based on customer requirements.


PNC not only offers full turnkey PCB assembly, but also integrating the printed circuit board assembly into enclosures. Our experience in box builds come in many different sizes, shapes and enclosure materials. Our capability of enclosure assemblies is from snap together plastic housing to metal form factors that require torque specifications.

  • Plastic/Metal enclosures
  • Mechanical assemblies
  • Kitting, labelling and packaging of finished product with all components and documentation
  • Direct ship to distributors or end customers


Our inspection process for SMT assembly starts right after screen printing with an in-line solder paste inspection station and after re-flow with Mirtec 3D AOI’s. If the printed circuit board assembly has BGA, QFN’s or other components with leads on the bottom of the part, we inspect 100% with a Glenbrook 3D X-Ray to identify solder deficiencies.

Other PCB assembly services we offer are Functional and Probe testing as well as programming of devices on your printed circuit board assembly. All functional testing and programming will be done according to customer test and programming procedure requirements.

  • 3D Solder Paste Inspection
  • 3D AOI Inspection
  • X-Ray Inspection with 3D capability
  • 100% Visual Inspection - High Magnification Digital Microscopes
  • Functional Testing with custom test fixture & Programming


  • Sheet Metal/Plastic Enclosures
  • Configuration
  • Conformal Coating
  • Cable/Wire Harness and Assembly
  • BGA Rework
  • ICT Test
  • Potting Services
  • Burn In, Temperature and Humidity Cycling
  • Others Available upon Request


  • Full Turnkey
  • Full Consignment
  • Partial Consignment


To comply with Moisture sensitive components, PNC utilizes a dry cabinet storage system. The humidity is controlled at 2-5% at a temperature of 22-25 C (71.6-77 F). All MSL level parts are stored either by Customer job number or by PNC’s MRP part indemnification numbering system. This practice eliminates component failures during the SMT assembly re-flow process.


Depending on the design of Panel array, PNC has 2 methods of de-panelization at the end of the PCB assembly. V-scored panels are de-panelized using a Fancort pizza style cutting blade which cleanly separates the array. When panel arrays are tab routed, PNC uses a router to remove the tab flush with the printed circuit board assembly and eliminates manual sanding of partial tabs.
