Next Generation Vacuum Soldering Systems

Neu Dynamics is proud to represent budatec GmbH – a leading machine manufacturer for the semiconductor and solar industry. Based in Berlin, budatec brings more than 20 years of experience in developing vacuum soldering technologies ranging from small R&D furnaces to fully automated soldering systems. They are recognized as a leader in this segment specializing in the use of hydrogen and plasma gases in their systems.

Budatec’s latest generation vacuum soldering systems continue to impress and offer increased flexibility, expandability and ease of integration.

Why Vacuum Soldering?

Vacuum soldering considerably increases yield in production. With better derivation of heat loss and integration of drying and degassing processes, this technology allows bonding surfaces to remain free from oxides and cavities resulting in little or no contamination on the product.

Other benefits include:

Integrated (or separate implementation of) cleaning and scaling processes
No degassing processes on the product
Different pressure areas can be created inside the sealed chambers
Sealing of chambers with a previously defined gas atmosphere
Assembly in high vacuum
Possibility of a further miniaturization

Budatec VS320i Vacuum Soldering System

First presented at productronica 2021 in Munich, the budatec VS320i Vacuum Soldering System builds on the success of the VS320. With the next generation VS320i, each furnace has its own automatic loading and unloading system. As a result, it is simple to integrate the ovens into an existing inline line via the conveyor system. It offers increased flexibility because several ovens can be easily linked in series allowing the line to be adapted to the production capacities. You get a fully automatic inline vacuum brazing system that is simple to expand. Several technology steps can be integrated inline quickly and easily.

Features of the system include:

1000x2000x1360 (w x h x d in mm)
Innovative swivel hood
Integrated Y-Z axis system
X-transport by servo-controlled conveyor belt, choice of 1 or 2 belts
Direction of belt variable, also possible from right to left
Optional automatic filling of the HCOOH container from a canister
Simple interlinking by means of SMEMA
Optional MES protocol: SECS/GEM, OPC-UA, etc.
Heating plate 320mm x 320mm
100mm chamber height
Vacuum up to 0.1mbar absolute
2K/s heating and cooling
N2
Optional N2H2 (95/5), HCOOH, H2 (up to 100%)
