Sized for your first run, not a large-EMS minimum

  • PCB assembly (PCBA) on its own, or the complete box build, assembly, firmware, enclosure, and testing
  • Batch sizes set to your first or low-volume run, not a high-volume minimum
  • Already an active market for us, alongside Hong Kong and other served countries
  • Design review before fabrication, so problems are caught before tooling starts
  • ISO 9001 quality process, with a report before every shipment
PCB assembly and box build production at CADLETE Designs

Our PCB Assembly & Box Build Process

The same process whether you need bare PCB assembly or a fully finished box build.

01

Design Review & DFM

Your PCB and mechanical files are reviewed for manufacturability before fabrication starts.

02

PCB Fabrication & Assembly

Boards are fabricated and populated, with automated optical inspection at each stage.

03

Firmware & Functional Test

Firmware is flashed and every unit is functionally tested, if firmware is part of your scope.

04

Enclosure Integration

For a box build, the tested PCBA is integrated into its enclosure, with connectors and sub-assemblies fitted.

05

Shipping to Singapore

Packed and shipped with full documentation, sized to your actual batch, not a large-EMS minimum.

Where This Work Applies

The product changes, but the same fabricate, assemble, test discipline applies across categories.

IoT Products

Connected devices and sensor systems shipped ready to pair.

Consumer Electronics

Smart devices and embedded interfaces built to retail quality.

Industrial Systems

Monitoring and automation hardware built for continuous duty.

Medical Devices

Embedded control and sensing systems, built to a documented process.

Mobility & Automotive

Embedded monitoring and communication hardware for vehicles and fleets.

Smart Infrastructure

Connected control and sensing platforms for buildings and sites.

What Singapore Founders Ask Before Their First Production Run

Our order is too small for the big EMS providers here, can you still help?

Yes. We work with founders on their first production run, not only high-volume repeat orders, so a batch size a large EMS provider would turn away is a normal starting point for us.

Do you already have experience working with Singapore-based clients?

Yes, Singapore is one of our active served markets, alongside Hong Kong and several other countries.

Can you do the PCB assembly only, or the full box build?

Both. PCB assembly on its own, or the complete box build (assembly, firmware, enclosure integration, and testing) if you need the finished product.

How do you handle IP protection for a Singapore-based client?

A non disclosure agreement is signed before any design file, schematic, or firmware is shared with our team.

Working with Cadlete Designs has been a real pleasure. They helped with so many design aspects I hadn't considered and offered many suggestions that I would have never thought of. Professional, prompt, and always willing to go the extra mile. I was extremely lucky to have found them! (Patent Pending)

These guys are simply the best. They are professional and on time with the orders and take great care in understanding what it is you want done. They offer revisions on the product if it is off and they are so pleasant to work with, I would 10/10 recommend them to anybody looking for designs drawn up.

I have been getting a ton of design work done. Engineered specs, renderings for the past 3 years with them. The best thing about them is that they come back quickly and with great work quality. I really appreciate all the work they done for us and continue to do.
