How a lot does it price to assemble a Prototype PCB?


When launching a brand new electronics {hardware} product, constructing prototype printed circuit boards (PCBs) is a vital step earlier than committing to full manufacturing. Prototyping permits validation of the design, testing of performance, and de-risking manufacturing.

Nevertheless, prototype assemblies can have excessive prices in comparison with excessive quantity manufacturing. It’s necessary to funds adequately and perceive what components drive prototyping bills.

This text will study typical prototype prices and what variables affect the general value. We’ll have a look at methods for optimizing BOMs, meeting choices, and approaches to scale back prototyping prices with out sacrificing high quality.

Typical Prototype Prices

Prototype construct prices can differ broadly based mostly on:

  • Board complexity
  • Invoice of supplies (BOM)
  • Sort of meeting
  • Order quantity
  • Testing necessities

For easy, low element rely boards, prototype prices usually vary from $$500 – $1500.

For complicated boards with a whole bunch of elements, prototypes can price $$5000 – $50,000+.

Excessive combine boards with many various element sorts will fall on the upper finish. Builds with costly processors or particular supplies additionally enhance prices.

Beneath we’ll break down the associated fee components in additional element.

Value Drivers in Prototype Meeting

The first drivers of prototype PCB meeting pricing embrace:

Board Fabrication

Base price of supplies, layer rely, and tolerances to bodily manufacture the naked PCBs. This ranges from $200 – $2000 per board for typical prototypes.


Complete price of the invoice of supplies (BOM) which should be sourced for the construct. This usually dominates total price.


Value of inhabitants together with labor, tools, and overhead. Usually $100 – $500 per board relying on complexity.


Expense of validation and inspection throughout meeting and after construct. From $50 – $500+ per board.


Complete variety of boards assembled. Value per board drops considerably with quantity.

Lead Time

Sooner turnaround calls for manufacturing prioritization and incurs premiums.


Added markup above base prices that meeting suppliers construct in. 10-30%+

NRE Charges

Non-recurring engineering expenses for web new setups and programming.

Let’s discover every of those main contributors to grasp how you can optimize for price.

Optimizing Board Fabrication Prices

The bottom fabrication of the naked PCBs themselves entails tradeoffs between price and functionality:

Greater Layer Depend – Provides processing steps and supplies expense. However permits dense, complicated routing.

Superior Supplies – Particular substrates for RF, flex, and many others price greater than FR-4.

Tight Tolerances – Holding tighter tolerances will increase tooling time andscrap price.

Excessive-mix vs Panel – Single boards price greater than panelized designs.

Onshore vs Offshore – Native fabs cost extra however keep away from delivery.

Quickturn – Sooner lead instances enhance labor and machine prices.

Methods to Scale back Board Fab Prices:

  • Standardize on generally used supplies like FR-4.
  • Use the minimal variety of layers that meets design guidelines.
  • Specify trade customary thickness and finishes.
  • Construct margin into tolerances for higher yields.
  • Panelize a number of boards when format permits.
  • Think about offshore choices for quantity manufacturing.
  • Plan early and keep away from quickturn companies if attainable.

Balancing efficiency wants and funds requires skilled engineering judgement.

Optimizing Element Prices

The BOM usually accounts for over 50% of complete prototype price. Each half provides up.

Strategies to decrease BOM prices:

  • Substitute costlier parts with cheaper acceptable alternates.
  • Consolidate designs to shared, excessive quantity parts the place attainable.
  • Scale portions based mostly on precise want for prototyping. Keep away from extra models.
  • Re-use current stock from earlier builds if accessible.
  • Leverage authorised vendor lists to get bulk pricing.
  • Keep away from costly sole-sourced or customized elements if attainable.
  • Examine alternate distributors for identical elements for price comparability.
  • Shrink element bundle sizes to save lots of prices.
  • Scale back variety of distinctive elements numbers and suppliers.
  • Negotiate pricing and MOQs with quantity commitments.

Every $1 half trimmed from the BOM provides up considerably throughout builds.

Optimizing Meeting Prices

The meeting course of itself represents a significant portion of complete price.

Suggestions for decreasing meeting bills:

  • Simplify total board format and cut back half counts.
  • Get rid of odd formed boards requiring particular fixturing.
  • Reducelayer transitions and vias requiring handbook steps.
  • Scale back or keep away from by means of gap element use which provides labor.
  • Maximize easy-to-place chip parts vs connectors.
  • Consolidate BOMs round widespread elements and packages.
  • Use customary SDAs for recognized good working margins.
  • Shift take a look at steps to suppliers’ decrease price places.
  • Evaluate a number of meeting distributors’ pricing.
  • Leverage current most well-liked vendor relationships.

General, optimizing designs for manufacturability lowers price and threat.

Economies of Scale with Quantity

Prototyping meeting pricing is extremely depending on amount. The extra boards ordered, the decrease the associated fee per board:

Amount Value per Board Complete Value
10 boards $1,500 $15,000
25 boards $1,000 $25,000
100 boards $750 $75,000
500 boards $500 $250,000

This displays spreading setup prices over extra models. Constructing a panel to assemble a number of boards concurrently additionally improves price.

Consider your quantity wants upfront and purchase in bulk if attainable. Further boards can be utilized for testing, demos, and many others.

Managing Lead Instances

Regular meeting lead instances vary from 2-8 weeks for prototypes. Dashing supply incurs substantial expediting expenses:

  • 2 Week Lead Time – 50-100% premium
  • 1 Week Lead Time – 100-200% premium

Keep away from quickturns except completely crucial to your schedule. Plan early with meeting companions to safe affordable lead instances.

Lowering Take a look at Prices

Testing is essential however provides price. Tailor take a look at packages to satisfy true wants:

  • Carry out design validation earlier than committing to prototypes.
  • Begin with a smaller pilot construct earlier than full quantity.
  • Align take a look at protection to threat profile of the design.
  • Execute checks on low price take a look at boards the place possible.
  • Restrict excessive price checks like shock, vibration to later refined models.
  • Outline take a look at go/fail standards upfront with suppliers.
  • Analyze failures totally and alter solely what is critical.
  • Think about take a look at engineering consulting to optimize program.

Proper dimension testing to match this system’s maturity degree.
