Gemini Tec is also known as 'G-Tec', we've been an innovative service provider since 1978. We are a privately owned and managed business with strong core values and a focused approach to long-term sustainability. Daily operations and strategic leadership is conducted through Managing Director Adam Harsant, supported by Operations Director Gavin Hughes-Keast and a team of over 55 dedicated specialist technicians and engineers.  


Our reputation was originally established in providing rapid PCBA prototypes, as we still do today. In more recent years the business has developed and adapted into a full CEM operation. 

Today we supply a fully comprehensive sub-contract electronics manufacturing service from our highly organised production facility in Hampshire. We are equipped with world class processing capability to support a wide range of customers and complex PCBA related products. 

Our long-term approach to investment allows us to provide the very latest manufacturing capability. Gemini Tec were the first UK CEM to adopt the solder jet printing across its entire SMT operation, providing unrivalled product quality and manufacturing reliability, and the first UK CEM to adopt Asscon's fully in-line vapour phase reflow technology.

Our core values.

  • Open and transparent relationships with customers and suppliers. 
  • Consistency in product and service quality.
  • Sustainable business ethics to ensure longevity for our staff and our customers.
  • Proudly conducting all our manufacturing operations in the UK.
