Manufacturer Capacity:

Electronic printed circuit board (PCB) manufacturing processes:
PCB material choice:
Common base materials include FR-4 (fiberglass), polyimide and ceramics
Consider properties such as dielectric constant, thermal performance, and flexibility
Special materials available for high-frequency, high-power or flexible PCBs

Copper thickness and layer count:
Typical copper foil thickness ranges from 1oz to 4oz (35µm to 140µm)
Single-sided, double-sided and multilayer PCBs available
Additional copper layers improve power distribution, heat dissipation and signal integrity

Surface Treatment:
HASL (Hot Air Solder Leveling) - Affordable, but surface may not be flat
ENIG (Electroless Nickel Immersion Gold) – provides excellent solderability and corrosion resistance
Immersion Silver - Cost effective for lead-free soldering
Additional options include ENEPIG, OSP and direct gold plating

Advanced PCB Technologies:
Blind and Buried Vias for High Density Interconnects
Microvia Technology for Ultra-Fine Pitch and Miniaturization
Rigid-flex PCBs for applications that require flexibility
High frequencies and high speeds with controlled impedance pc

PCB manufacturing technology:
Subtractive process (most common) - etching away unwanted copper
Additive process - creating copper traces on the base material
Semi-additive process - combining subtractive and additive technologies

Design for Manufacturer (DFM):
Adherence to PCB design guidelines for reliable manufacturing
Considerations include trace width/spacing, via size and component location
Close collaboration between designers and manufacturers is essential

QA and testing:
Electrical testing (e.g., online testing, functional testing)
Mechanical testing (e.g., bending, shock, vibration)
Environmental testing (e.g., temperature, humidity, thermal cycles)
