How Standard PCB Specifications Help You Control Cost

Most of a PCB’s price is decided before it reaches fabrication, in the specifications you choose. Material, thickness, copper and finish each either stay within a standard build or move outside it.

This guide shows which specifications drive cost, what PCB Power’s standard build looks like, and when it is enough for your design.

Which PCB Specifications and Options Drive Cost?

Lead time is the easiest one to adjust late in a project: if your schedule has room, a longer lead time lowers the cost. On our Instant Quote page, you can compare cost for different lead times and quantities side by side.

Board size and quantity also affect price, but they come from your design and order rather than your specification choices.

How Much Can You Save with Standard Specifications?

Switching from custom to standard specifications can save you up to 45% on PCB cost.

Actual savings depend on your quantity, layer count, board size and delivery format (single boards or panel). Compare quotations for both configurations to see the difference for your design.

These options apply to single-sided, double-sided and compatible multilayer boards. For multilayer orders, confirm layer arrangement, inner-layer copper and impedance requirements separately.

You do not need to customise every specification because one requirement is different. Keep the standard options that suit your design and change only what your application requires.

When Is Standard Enough, and When Should You Customise?

Material. Normal-Tg FR-4 is a practical starting point when it meets your electrical, assembly and operating requirements. Tg is the glass transition temperature, not the maximum operating temperature. For higher temperatures or demanding assembly cycles, review the complete laminate properties. See PCB materials and specifications.

Thickness. Keep 1.6 mm when it fits your enclosure, connectors and mounting. Change it when mechanical fit or stackup requires. For multilayer boards, overall thickness must match the required stackup.

Copper. Standard 35-micron finished copper suits many designs. Move to heavier copper when current, voltage-drop or temperature-rise calculations justify it. Finished copper includes plating where applicable.

Surface finish. Leaded HASL is standard where your components and product requirements permit it. It contains lead, so for RoHS products choose a lead-free finish unless a valid exemption applies. Fine-pitch parts and BGAs may need a flatter finish such as ENIG; follow package guidance.

Colours. Green mask and white legend are standard. Change them only for optical, branding or identification needs.

Customise when it counts. Keep custom specifications for real requirements: demanding thermal conditions, high current, mechanical constraints, lead-free requirements or fine-pitch assembly. RF and high-speed designs need careful material and stackup selection. Controlled impedance does not automatically require a specialised laminate; suitable FR-4 constructions can support it with appropriate geometry and material control.

The right configuration is the one that meets your requirements at an appropriate cost.

Whichever you choose, make sure your Gerber files, fabrication notes and quotation selections match. See our design guidelines and pre-production engineering checks.
