Electronic Assembly Services
Low-volume electronics assembly services for supplied PCBAs, harness integration, connectorization, through-hole soldering, and mechanical assembly.
We are not an SMT or reflow shop. We help when the electronics are real hardware on a bench: boards, wires, connectors, enclosures, labels, and functional checks that need to come together.
Case Study
Supplied Boards, Finished Prototype Assemblies
A controls team had tested PCBAs but needed through-hole connectors installed, harnesses built, labels applied, and enclosure hardware prepared before a pilot demo.
We handled the connector work, harness integration, mechanical assembly, and functional checks while keeping the customer-supplied PCBAs controlled.

Pricing depends on soldering points, harness complexity, enclosure work, component sourcing, inspection level, and functional test. Send the inputs below so we can quote the full job after review.
What to Include for a Fast Quote
- Through-hole or PCBA integration scope
- Drawings, photos, or samples
- Solder points and connector list
- Quantity and inspection level
The Problem
The Board Is Only Part of the Assembly
PCBAs Need Interfaces
Boards still need connectors, wires, labels, mounting, strain relief, and test access.
SMT Shops Stop Early
A board house may not want the messy harness and enclosure work around the PCBA.
Prototype Builds Change
Low-volume electronics builds need fast feedback when a connector, label, or route is wrong.
The Solution
Contract Assembly Built Around Harnesses
MiniProto combines through-hole soldering, connectorization, PCBA-to-harness integration, and mechanical assembly for prototype and low-volume electronics.

Electronic Assembly Capabilities
Honest Scope for Low-Volume Hardware
Through-Hole Soldering
Hand soldering for connectors, headers, switches, leads, and components that fit low-volume electronic assembly.
PCBA-to-Harness Integration
Install supplied PCBAs into harnesses, enclosures, panels, and electromechanical assemblies.
Connectorization
Crimped, soldered, ferruled, and terminal-block interfaces between boards, harnesses, panels, and devices.
Potting Prep
Wire routing, masking, strain relief, and assembly preparation before customer-specified potting or encapsulation steps.
Mechanical Assembly
Standoffs, glands, switches, fans, brackets, labels, and enclosure-level hardware installed around the electronics.
Ultrasonic Wire Splicing
Gas-tight welded wire joints are our house-default splice method for low-resistance harness integration.
Process
From Supplied PCBAs to Tested Assemblies
Scope and Inputs
We review drawings, PCBA handling needs, harness details, soldering requirements, enclosure constraints, and test expectations.
BOM and Build Plan
We identify customer-supplied PCBAs, sourced components, harness items, labels, and operations that need approval.
Assembly
Through-hole soldering, connectorization, harness integration, mechanical installation, and potting prep are performed to the released scope.
Inspection and Test
Visual checks, continuity, basic functional checks, and customer-defined acceptance steps are recorded when scoped.
Revision Feedback
Prototype findings are returned as sourcing, wiring, or assembly notes for the next build.

Electronic Assembly FAQ
Common Questions About Electronics Assembly Services
Do you offer SMT assembly or reflow?
No. MiniProto does not claim SMT placement or reflow capability. We integrate supplied PCBAs and handle through-hole, wiring, connector, and mechanical assembly work.
What electronic assembly services are a good fit?
Through-hole soldering, PCBA-to-harness integration, connectorization, potting prep, enclosure wiring, and low-volume contract assembly are good fits.
Can you build cable and harness assemblies as part of the electronic assembly?
Yes. Harness fabrication is one of MiniProto's core capabilities, so board-to-device wiring can be built with the assembly.
Can you source components?
We can source common wire, connectors, terminals, hardware, labels, and assembly materials. Customer-controlled PCBAs are usually supplied by the customer.
Do you test assemblies?
We can perform continuity, visual inspection, power-up checks, and customer-defined functional test steps when included in the quote.
Are you a high-volume contract manufacturer?
No. MiniProto is strongest for prototypes, pilot builds, and low-volume contract assembly services.
