OurPCB’s current website presents a broad custom assembly offering rather than only a bare-board checkout. It covers PCB manufacturing, multiple assembly methods, low- and high-volume work, turnkey sourcing and related wiring services. For a buyer, the useful question is whether those services can be defined as a controlled build package with clear responsibility from incoming components to the accepted assembly.
Editorial scope: PCBPit is a manufacturing service provider. This review assesses the supplier’s published offering and purchasing workflow; it is not a factory audit or a hands-on production test.

Custom assembly starts with the delivery boundary#
A populated PCB, a wired subassembly and a finished product are different deliverables. For an illustrative industrial sensor, specify whether the order includes the sensor lead, connector termination, mounting hardware, firmware and final label. If one item is omitted, the customer may still need a separate assembly operation after receiving the boards. Ask for a responsibility list that includes supplier-provided and customer-provided items, and identify who approves mechanical changes.
Mixed technology creates process questions#
OurPCB lists SMT, through-hole and other assembly services. A board with surface-mount ICs and large through-hole connectors needs more than a component count. Clarify which operations follow reflow, how tall parts are handled, and how connector alignment is checked. Consider whether cleaning, coating or selective soldering is required and whether the component materials tolerate the proposed process. The assembly process guide helps turn these requirements into an ordered manufacturing sequence.
Turnkey sourcing does not transfer design authority#
Letting a supplier buy parts can reduce purchasing work, but the approved BOM remains the design authority. Establish acceptable manufacturers, package variants and substitution rules. A replacement connector may fit the PCB yet change mating compatibility; a substituted capacitor may meet nominal capacitance but behave differently at operating voltage. Keep alternate approval in writing and use the BOM guide to record exact manufacturer part numbers and requirements.
OurPCB is worth considering when an assembly needs customized sourcing and integration discussions. Compare WellPCB for another board-and-wiring offer and PCBCart for high-mix and box-build positioning. For a startup batch, use the low-volume assembly checklist and request the same defined scope from PCBPit. Website service breadth alone does not establish quality or a lower delivered cost.
Make the quotation comparable#
Use one controlled release pack for every bidder: Gerbers and drills, fabrication drawing, stack-up, assembly drawings, BOM and placement file where applicable. Separate board fabrication, parts, setup, assembly, testing and freight. Record the approved revision and all exceptions before paying. A low board price does not establish a low delivered cost, and an inspection list does not establish functional test coverage. Ask who supplies test fixtures, firmware and acceptance limits; agree how shortages, substitutions and failed units will be handled.
Questions buyers ask#
Does turnkey mean every component may be substituted?
No. Define approved alternates and require written authorization for changes outside that list.
Is a wired subassembly a finished product?
Only if the delivery scope includes every required mechanical, programming, test and packaging step. Define acceptance at the actual product boundary.
What should be checked on mixed-technology boards?
Process order, component temperature limits, connector alignment and the inspection method for each joint type.
How can a first order reduce repeat-build risk?
Retain the approved build pack and test results, document deviations and close corrective actions before increasing quantity.
