Outsourcing the procurement process allows customers to benefit from our experience and commercial leverage. We can procure the complete inventory ensuring the conformance of components and products and removing the risk of counterfeit or sub-standard parts. Materials are sourced, delivered, checked, and presented correctly to our production departments ready for production, free of delay.G-Tec Secure & Bonded Stores

Gemini Tec use MRP and a site wide system integration to manage its materials and inventory. All items are bar-coded using a unique carrier upon arrival, allowing us to move and track each item within our facility. We can monitor and control all MSD devices, from exposure times to baking and re-sealing. 

The key aspects of our materials service:

  • Approved suppliers, using ISO900, AS9100 & ERAI Members
  • Device testing to AS6081
  • MRP BOM importing with MPN matching
  • Common branded R&C's in stock
  • Traceable component stock by batch number to supplier
  • Obsolete component sourcing
  • Proven supply chain in printed circuit boards
  • RoHS and Non-RoHS device procurement
  • Scheduling & expediting
  • Quality & conformance checking
  • MSD handling, baking & shrink-wrapping (IPC/JEDEC J-STD-033B) 


We have access to a network of global suppliers and manufactures, from bare PCBs, board level components to metal enclosures and manage supplier performance and product quality on your behalf. Our system is compliant for full traceability, detailing all batch movements and issues through all locations - back to the finished serial number. 


Blank PCB manufacturing


The quality of the raw PCB is critical to the quality of manufacturing operation, and our knowledge and in-house technical expertise will ensure this key component is manufactured to the correct specification. 

We have in-house engineers using Barco U-Cam tooling software to generate and check the PCB tooling. By completing this process in-house, we can ensure your PCB data passes numerous checks (DRC, DFM and netlist check) including verification of the impedance layer stack up and raw material selection. Any suspect or technical issues can be addressed and removed prior to fabrication and before any components are placed.

We are fully conversant with a full range of PCB technologies from standard rigid multilayer boards to flex and flex-rigid boards. 

PCB manufacturing technology includes

  • Multilayer technology 4-40 layers, controlled impedance, mechanical/laser drilling, LDI printing
  • Fine trace and space: 2.5/2.5 Mil, with hole aspect ratios up to 20:1
  • PCB laminates, High Tg FR4, HR370, IS410, P95, Rogers, Taconic, Arlon


In addition to data engineering we off a full reverse engineering and artwork scanning service to support legacy products and corrupt data.


Automated Material Handling & Loading

Components loaded onto our SMT line at Gemini Tec

Our integrated material system provides full track and trace capability. Every reel, tape, stick, box, tube, tray is supplied with a unique bar-code, or carrier ID. This allows us to scan every item to ensure it matches our customer BOM, before being placed into a unique ESD tote relative to a customer order. 

All ESD totes are subsequently scanned at various locations in our facility, allowing us site wide visibility to every component.

This unique bar-code produces a 'data set' which is seamlessly passed into our SMT production environment to deliver the ultimate in production efficiency.

  • The fastest set up times on our SMT lines
  • Correct feeder assignment and position
  • Electrical test of components
  • Counting of components used
  • Managing MSL exposure times for MSD items

Once the materials have been removed from the SMT lines, any carrier ID's can be scanned to ensure inventory on hand is updated or replenished.

Our advanced Mycronic SMT placement lines operate with intelligent Agilis feeders, which means we are able to accept cut tape, over full reels. Working with cut tape allow us to limit material usage and wastage and is just one small feature or our agile service. 

To help is import your BOM and optimise the build process, please download our recommend BOM format: G-Tec Example BOM. 


Free Issue Materials

In some cases, customers need to provide us with materials on a free issue basis. We transact these items as a purchased part, so we can provide the benefits of our material handling system to manage the quality and delivery. All consigned materials can be stocked, tracked, and managed in our customer specific storage locations at Gemini Tec. We can provide stock reports, working with a FIFO basis and ensure minimum stock levels are maintained.

We are happy to accept 'Full Free Issue Kits' and provide you the benefits of our material handling system, however we need to request the materials are supplied in a suitable format. We strongly recommend early engagement with us to discuss this level of detail and avoid any confusion which may cause production delays.    

If you are considering supplying the 'blank PCB's' as a free issue item, please contact us. We can provide you the correct engineering support to ensure the quality of your product is not compromised.
