Question 1

How accurate is this calculator?

Accepted Answer

This calculator provides a rough estimate based on typical pricing factors. Actual costs may vary by ±20% depending on design complexity, special requirements, and current production capacity. For accurate pricing, please submit your Gerber files for a formal quote.

Question 2

What factors affect flex PCB cost the most?

Accepted Answer

The main cost drivers are: 1) Layer count - more layers significantly increase cost, 2) Board size and quantity - larger volumes get better unit pricing, 3) Material type - polyimide is more expensive than FR4, 4) Surface finish - ENIG and hard gold cost more than HASL, 5) Lead time - rush orders carry premium charges.

Question 3

Why is flex PCB more expensive than rigid PCB?

Accepted Answer

Flex PCBs require specialized materials (polyimide), more complex manufacturing processes, and additional steps like coverlay application. The flexible substrate is inherently more expensive than FR4, and handling thin, flexible materials requires specialized equipment and expertise.

Question 4

How can I reduce my flex PCB cost?

Accepted Answer

Consider these strategies: 1) Optimize board size to fit standard panel sizes, 2) Reduce layer count if possible, 3) Use standard trace widths (4mil+) instead of fine pitch, 4) Choose HASL over ENIG if gold isn't required, 5) Order larger quantities for volume discounts, 6) Allow standard lead time instead of rush.
