We are renowned experts in SMT production, with a solid reputation for on-time delivery. Our service is best suited to customers seeking high quality NPI products, prior to production. 


Our dedicated NPI department currently engineers and manufactures over 800 new NPI orders every year, making us unique in high mix manufacture. Our capability is configured to deliver unrivalled speed and reliability for complex PCBA's. We have invested heavily in world-class process capability, such as ‘solder jet printing' and vapour phase reflow, to provide a superior level of quality for complex PCB assemblies, using BGA, uBGA, QFN, DFN and PoP devices. 


Commercial elements of our rapid NPI/prototype service:

  • Dedicated rapid delivery service.
  • Build standards IPC class 2 or 3, by accredited technicians 
  • Rapid delivery batch builds for 1 to 100 units.
  • Full turnkey orders, including BOM materials and blank PCB's substrates.
  • Complex capability and engineered solutions, for demanding development programs. 


Technical advantages:

Main PCB area at Gemini Tec

  • Dedicated Mycronic SMT placement lines.
  • Dedicated solder jet printers.
  • Dedicated vapour phase reflow, with vacuum processing for complex PCBA's.
  • Sub 0.3 mm BGA, PoP, leadless, 01005, 0201, 0402, QFN, DFN etc.
  • 100% validation with 5-axis Mirtec AOI inspection tools.
  • Full inspection with X-Ray & optical cameras.
  • World class process capability for high yield and right first time.


To ensure product validation we use a range of comprehensive tools, such as, Mirtec five axis camera AOI systems, fibre optic Ersascope cameras and 3D X-Ray.


Skilled IPC technicians are used to complete any second stage assembly, by hand or with automated soldering machines. Products can be cleaned using ultrasonic or aqueous washing methods. In-house conformal coating is available with our controlled spray booth for fast track orders. 


Your ODB++ data is used to create all the digital tooling using Aegis Factory Logix. All engineering is completed by experienced staff who check and plan all aspects of the production flow, including the use of Barco tools for DFM/DRC on your Gerber data prior to build. You can view our tooling data requirements by downloading our fact sheet here.

Powerful MRP software is used to organise and procure materials together with planning the manufacturing workflow. All component inventory is managed through our material handling system, with the use of intelligent bar-codes to provide a range of unique features:


  • All the materials are scanned into ESD totes to track and trace their location and quantity consumed during the production process.
  • Technical data is passed seamlessly into our SMT machines for numerous benefits:
    • To configure the most efficient 'set up' time and build process.
    • Validate the correct components have been presented to the SMT line. 
    • Conduct electrical test to various SMT components.
    • Correctly track & manage MSL related activity, such as exposure times per component.


Our bespoke e-TMR software is used to capture shop floor data for live production updates, including the status of all components used and operations completed.

e-TMR allows us to communicate and control sensitive instructions directly with any of our team, when works orders are in progress. This highly effective two-way system allows us to collect, store and share valuable information for internal process improvements and also with customers for product design improvements.
