Gemini Tec Ltd - PCB Design Layout Services

At the centre of our surface mount operation is the very latest in SMT placement technology.

Our MYDATA Synergy line is equipped with two MYDATA placement machines, working in-line for high speed SMT production. This leading edge line has automatic board loading and full conveyance from pasted PCB board to oven reflow.

Using the MYDATA "Synergy" approach we can provide a flexible production service, by building SMT boards across 1 or 2 placement machines. This scalable and flexible approach allows us to build surface mount products from 1 to 10,000 pcs.

• Complex high mix PCB assembly.
• MYDATA Synergy approach for flexible production.
• Automated line, for optimum production costs.
• Jet printed solder paste, for high yield soldering.
• High technology surface mount product assembly.
• BGA, µBGA, 01005, 0201, PoP and Leadless devices.
• In-line electrical test on resistors & capacitors.

The automated Synergy line is supported by our MYDATA solder jet printer, providing pasted PCBs on demand. Only the correct amount of paste is applied to each footprint to ensure the optimum reflow conditions are achieved for high product yields. PCB assemblies are buffered and shuttled across the Synergy line conveyors within minutes of solder paste printing.

We use the latest MYDATA operational & productivity software to maximise production up time and optimise the cost of manufacture.

We operate a sophisticated and automated process to selectively coat PCB assemblies. Utilising our leading edge PVA coating system, we can selectively coat PCB assemblies with a wide variety of conformal coating products.

Robotic spraying allows fine amounts of coating to be selectively dispensed onto PCB's with high accuracy. Multi axis control allows the coating to sprayed on, around and underneath complex components. The distinct advantage of this technique means there is no longer a need to mask the keep out areas of the PCB. Selectively spraying allows a price point typically 20% to 30% lower than traditional coating methods.

We clean our products to exceed the guidelines of IPC CH-65 A and J-STD 001-D, also known as MIL SPEC. We use Zero Ion contamination testing to ensure the level of cleanliness prior to coating.

• Robotic and selective spraying system.
• No Masking required.
• Fine line definition.
• Spraying for accurate viscosity of coating.
• Spraying for accurate thickness of coating.
• 100% repeatable process.
• Pneumatic tilt axis for spraying underneath components.
• Full cleaning process to meet J-STD 001-D (MIL SPEC)
• Full cleaning process to meet IPC CH-65 A.
• Ultrasonic & vapour solvent cleaning.
• Ionic testing facility, with Zero Ion.

Gemini can provide its customers with fully coated PCB assemblies, as part of its turnkey operation or post test. As we use a fully automated selective process this can be supplied at cost effective rates.

Gemini Tec Ltd are the first UK based CEM to introduce 'Solder Jet Printing' for high density PCB assembly.

Our MYDATA MY500 is the revolutionary SMT technology process that applies solder paste directly onto the PCB. We no longer need to use stencils for surface mount production.  Over 80% of typical production errors are attributed to poor solder paste application, 'Solder Jet Printing' provides the technical solution.

Solder paste deposits are placed on demand at rate of 1.8 million dots per hour. Only the optimum amount of solder paste is applied to each pad position on the PCB, crating the ideal reflow conditions. The result ensures all the typical production errors are now removed (problems such as floating QFNs, excessive solder, short and opens etc) PCB products with surface mount products are manufactured with high yield results.

The use of 'Solder Jet Printing' has many commercial & technical advantages for Gemini Tec and its customers.

• 100% accurate and 100% repeatable, without deviation.
• No stencil tooling costs on new, repeat of modified designs.
• Optimum solder joints produced, with typical yields of 100%.
• Tooling and process development conducted in real time.
• Reduced manufacturing lead times.
• Reduced manufacturing costs.
• Suitable for complex & high density designs.

‘Solder Jet Printing’ technology is used across the entire manufacturing process at Gemini Tec. All our customers benefit from this leading edge technology regardless of the quantity we produce.
