Developing Custom Electronics Testing & Integration Solutions
Many of our clients benefit from our custom electronics development services, particularly bespoke test jig design. We create tailored hardware testing systems that verify every function of your product. These systems often integrate with custom PC software for automated control, test logging, and even on-the-spot result printing (one system includes a label printer for individual product reports).
During development, we frequently help clients untangle complex or temporary wiring setups. Using our in-house PCB design and manufacturing capabilities, we can transform wire nests into clean, efficient interconnection boards, designed for scalability and reliability.
All our work is carried out in our fully RoHS-compliant Kent-based facilities, where we offer Surface Mount (SMT), Through-Hole assembly, and complete electronic product builds.
At Winter & Smith, we push innovation beyond the screen by 3D printing your circuit boards before full production. This hands-on preview lets you see, hold, and test the design, checking size, layout, and connector access in real-world conditions.
It’s more than just a prototype, it’s peace of mind. You’ll know everything fits and functions as it should before a single component is assembled. It’s just one of the ways we go further to give you total confidence in your design, right from the start.
