ERSA Hotflow reflow oven with N2 at Gemini Tec Ltd

At our advanced manufacturing centre, our flagship surface mount line is fully enabled to manufacture complex PCB assemblies, including HDI and ultra-complex SMT technology.

As the density of HDI products increases, the addition of Nitrogen (N2) into the reflow process achieves a higher level of joint integrity. Injecting Nitrogen (N2) into the SMT reflow process prevents any oxidisation occurring increasing joint wetting on complex SMT components.

Using Nitrogen (N2) removes the risk of creating solder balls and HIP (head in pillow) which can occur under BGA and leadless devices where pin terminations are physically small. 

The ERSA Hotflow nitrogen reflow over was chosen as the ideal partner for high production throughput using 9 zones (7 heating/2 cooling) of complex SMT and PCB production. Advanced thermal management tools allows us to simplify the manufacture of products using high thermal mass and thin substrates (flex and flex-rigid products) 

This latest reflow capability is assigned to our flagship 'Trilogy' surface mount line. This SMT line is unique to the UK, combining the use of three SMT machines that can use 24 placement heads to build products in unison. This SMT line uses our MY700 twin head solder jet printer, to deliver type 6 solder paste and provide the ultimate in high mix PCBA assembly capability. 














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