Gemini Tec are fully equipped with world class production capability. Our flagship SMT line is fully enabled for HDI and ultra complex PCBA production, using the latest ERSA Hotflow nitrogen (N2) reflow oven from ERSA in Germany. ERSA Hotflow reflow oven with N2 at Gemini Tec Ltd

As the density of HDI products increases the addition of Nitrogen (N2) into the reflow process achieves a higher level of joint integrity.

This is achieved by injecting N2 into the reflow process to prevent the oxidisation of components during the ramp up phase. N2 provides improved wetting of solder joints and removes the risk in generating solder balls and HIP (head in pillow) under BGA and leadless devices, where pin terminations are physically small.

The ERSA Hotflow was chosen as the ideal partner for high production throughput using 9 zones (7 heating/2 cooling) with full support for high thermal mass PCBs and thin substrates (flex and flex-rigid products) using advanced thermal management tools.

This latest reflow capability is assigned to our flagship 'Trilogy' surface mount line. This SMT line is unique in the UK, combining the use of three SMT machines and 24 placement heads to build products in unison for the ultimate in true high mix capability.ERSA Hotflow N2 Oven close up at Gemini Tec Ltd

Gemini Tec support a wide range of applications from NPI to medium volume production. Our investment in advanced processing technology allows us to build complex and demanding PCBA products when reliability and quality conformance is mandatory.
