A printed circuit board (pcb) mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. pcb's can be single sided (one copper layer), double sided (two copper layers) or multi-layer. Conductor on different layers are connected with plated-through holes called vias. Advanced PCB's may contain components - capacitors, resistors or active devices - embedded in the substrate.
Below are some images from the printed circuit board manufacturing process. Including, drill, plating, and final fabrication. All the circuit boards go through intensive testing and quality control during each step of the manufacturing process.
Automated Optical Inspection (AOI)
Using the latest in optical inspection equipment on internal and external layers allows for minimal fallout on final product.
Final Fabrication (Routing & Scoring)
Routing and scoring to precise dimensions within supplied tolerances are the final steps prior to electrical testing. Constant monitoring by engineering ensures parts will meet your specifications.
Electrical Test
Flying Probe testers are used to 100% electrical test all PCB's on site at manufacturing.
Inner Layer
Inner layer core shown after etch\dryfilm strip processes have been completed. The core is now ready for post etch punch.
Laser Drill
Laser drill is necessary for today growing technology, drilling the smallest micro-vias using a beam of light 20 microns (1 Mil) in diameter. High influence beams can cut thru metal and glass creating the tiny via hole.
Post Etch Punch
Punching core material is the only acceptable method of building precision tooling which must remain accurate in a production atmosphere.
Press Room
Press lines for manufacturing quality, high layer count PCB's with consistency and in a timely manner.
Drill
CNC machines are complete with drill and profile routing software allowing for high performance and throughput.
Plating
Automated plating lines serving quick turns and production of small to high volume.
Strip - Etch - Strip Line
Production panels proceed to etching to remove unwanted copper and into the strip line to remove protective film.
