PCB Manufacturing Process

What is the Cost of Flexible PCBs?

On average, flexible PCBs can range from $0.50 to $5.00 per square inch for standard designs and materials. However, this cost is not fixed and can vary based on several factors. The factors that influence the price include necessary assembly labor, prevailing labor rates, and the time required for assembly. Additionally, overhead manufacturing expenses and the design complexity of the board play significant roles in determining the final cost.

Factors Affecting Flex & Rigid-Flex PCB Costs

Physical Size: Larger PCBs cost more, calculated per square inch.
Circuit Construction: Costs depend on materials, layers, and pads. Extra layers or high-quality materials increase costs.
Volume: Higher volumes result in higher costs.
Layers: More layers mean higher assembly costs. Opt for single-sided FPCBs if possible.

Finishing: Premium finishes guarantee longevity but come at a higher price.
Holes: More or smaller holes drive up costs due to increased drilling complexity.
Flex Board Types: Layer count influences price significantly.
Custom Features: Specifications like solder mask clearance, side plating, or contoured edges add to the cost.

How to Reduce PCB Production Costs

Minimize flexible layers, as rigid laminates are more cost-effective.
Reduce overall layers to lower the need for additional materials.
Limit controlled impedance requirements to necessary values only.
Opt for flexible copper thickness, approximately 1/3 oz.
Purchase FPCBs in bulk to reduce unit cost.

How are Flex & Rigid-Flex PCBs Manufactured?

Laminate Formation & Preparation

Step 1: Fabricate flexible laminates by bonding copper to PI film
Step 2: Laminate coverlay and copper foil

Drilling & Plating

Step 3: Drill holes for vias and through holes
Step 4: Electroplate holes to form conductive vias

Circuit Patterning

Step 5: Image and develop photoresist for circuit pattern
Step 6: Etch away unwanted copper
Step 7: Strip photoresist and apply solder mask over bare copper

Solder Mask & Surface Finish

Step 8: Expose and develop a solder mask
Step 9: Cure solder mask and apply surface finish

Shaping & Marking

Step 10: Punch or route PCB to final shape
Step 11: Print silkscreen legends and conduct electrical tests

Final Processing & Packaging

Step 12: Singulation and packaging
