In the UK

At Lutterworth, UK, JJS Manufacturing has 5 Mycronic pick and place machines arranged in 3 independent lines with the emphasis on high mix, low to medium volume, high complexity assembly. Currently placing between 2 and 3 million components per month, we operate 2 shift patterns (6am-2pm, 2pm-10pm) to ensure flexible availability of capacity.

Ongoing investment in equipment coupled with a proven ability to manufacture high reliability assemblies means that we are equipped to work with all surface mount packages.

In addition, there is an array of equipment for inspection, re-work and moisture sensitive device handling and storage, plus a fully equipped test department, including flying probe and In-Circuit test systems.


In the Czech Republic

At Chomutov, we have dedicated assembly lines, plus a broad level of skills for ‘conventional’ through-hole pcb assembly, with facilities for both leaded and non-leaded processes.

Our customers have continuing demand for this technology and, accordingly, we continue to invest in people, processes and equipment to support this requirement.

Given our breadth of electrical and mechanical skills and capabilities, both the UK & Czech facilities have dedicated areas for assembly and test of electro-mechanical products, cabinets etc, equipped with lifting and handling equipment for large cabinet suites and engineered products.

The Czech facility also has cable assembly cells equipped with an array of automatic cable cut & strip and automatic crimp machines.
