As the brains behind a number of common electrical devices, printed circuit boards connect electronic components through imprinted copper pathways. Most manufacturers either accept customer-created design files or help design and layout the printed circuit boards from a prototype.
Due to intricate layouts, the difficulty and cost in designing a printed circuit board far outweighs a traditional wired component circuit board. However, the actual fabrication, especially for high-volume production, is cheaper and faster. Some manufacturers cater specifically to smaller companies needing help through the design process and lower quantities of products produced.
By taking advantage of these types of manufacturers, companies can keep their initial costs down.
The fabrication process progresses through these general steps:
The physical layout is designed with software and tested virtually, or a prototype is created by hand and then captured by software. Both methods create a blueprint of the wiring.
Crucial decisions about number of layers, coating material and size are made, based on application.
An initial printed circuit board is produced.
The product is tested in its real-world application to see whether the schematic or design needs to be modified.
The final printed circuit board is produced in the requested volume.
After the actual fabrication, the manufacturer performs an electrical test and inspection before packaging to ensure that the final product is safe and meets the required UL and government standards. Precision Tech works closely with customers through each stage of the process to assure that each printed circuit board produced meets the customer's need and meets the applicable safety standards.
