Gemini Tec have installed and commissioned its second Asscon vapor phase reflow oven, and the UK's first VP2000 fully in-line reflow oven.

Our latest oven has now been added to our MYcronic MY200 Synergy SMT line, along with our MY600 solder jet printer. The investment vastly increases our reflow capacity and capability enabling a wide variety of product volumes to be produced. Our MY200 line is currently fully equipped with NuTek loading and unloading and uses fully automated transport conveyors to deliver bare boards through the entire SMT build process, removing any risk of handling defects.

Vapour Phase Reflow at Gemini Tec


This latest round of investment provides a fully in-line and automated process for vapor phase reflow, ensuring Gemini Tec remain at the forefront in manufacturing complex PCBA's for its growing customer base and batch sizes.

Gemini Tec initially adopted vapor phase reflow in 2015 and have once again chosen Asscon to provide its latest investment, who were pioneers in this leading edge process and lead the market in vapor phase reflow.

  Major benefits of vapor phase reflow:

  • No more overheating of the assemblies, because the boiling point of the heat transfer fluid defines the maximal soldering temperature. Therefore vapor phase soldering is ideally usable for lead free solder processes.
  • Continuous heating-up at the complete assembly even with different assembly parts and assembly mass.
  • Oxygen free soldering process without application of any protective gas.
  • Efficient use of energy due to the high heat transfer coefficient of the medium, compared with air, nitrogen or radiation. Therefore operating costs are significant reduced compared with the other Soldering Technologies as radiation and convection

Gemini Tec have confirmed another investment into vapor phase reflow technology for 2018.

The UK's first VP2000 line will be added to its MYcronic MY200 Synergy line shortly, increasing capacity for all series production orders. The investment forms part of a series of technology upgrades through 2018 & 2019. The choice to add more capability has been taken due to the outstanding results of its Asscon VP800 vapor phase reflow oven.     

Commenting on the latest news, Adam Harsant:

"We've had great feedback from our customers over the last year, since we installed our VP800 system and started to produce high complexity boards with this process. Now we feel the time is right to invest heavily in this technology to process our series production orders using the same process. And with our surface mount lines being fully automated, we now need to balance our production times for our higher volume orders "

"This reflow capability has already provided many distinct process advantages, but has also driven up the efficiency by removing the traditional problems found with creating and engineering oven profiles"

Gemini Tec Coating Spray Booth As part of our ongoing development and expansion, we've upgraded our process lab. Within this ESD controlled area we updated capability and capacity in key areas:

Conformal Coating Gemini Tec Automated Conformal Coating:
We've upgraded our spray booth, so we can coat small quantities quickly. When your batch sizes increase, we can use our automated PVA selective spraying system, allowing us to provide the maximum flexibility to changing production needs. 

Automated Wave Solder:
For PTH boards and second stage assembly (including double sided SMT) using our CMS400 wave soldering machine.
We use ultrasonic (with vapour) and aqueous techniques to prepare boards for coating or provide ultra clean PCBA's

We have 5 options for board breakout, including two routing machines to supply fully flush edges on your PCBA's. We always recommenced against using 'V-Score' techniques and have all the tools to support many breakout options.
