Final Assembly

Here at ESD we know that the term ‘Final Assembly’ has a different meaning for each and every one of our customers. As such please discuss what your requirements are. We can dispatch products after any production stage, at customer request. For example after surface mount is complete, or perhaps a partial build. We can also completely build and test products and pack ready for dispatch.

Hand Assembly

Automatic machine fitting of components is not always possible. For example, some components are too heavy or awkward, indeed not all are available in production packaging. Our skilled operatives hand fit these items, and then inspect each assembly to ensure that customer specification is met.

ESD assembly experts helped me through the entire process of our build. The quality was superb and all timescales were not only met but exceeded, I recommend ESD to anybody who is after a quality and positive service.

Each surface mount assembly is inspected using AOI (Automatic Optical Inspection) equipment. This inspection includes the component location, type, value and also it’s orientation.

At ESD each inspection is carried out by our team of experienced professionals who aim to ensure that all products exceed customer expectations upon dispatch. Once each build passes the highest form of inspection it next moves to our testing or final assembly team for a final check.

Upon request ESD test the final electronic assembly to your specification. We use our own test equipment for many products, however for more complex test procedures we use bespoke equipment. Please get in touch if you’d like us to build test equipment to suit your product’s individual test requirements.
