VSU12
Programmable vacuum reflow soldering oven with heating area 100x100mm.
Configuration
| Vacuum pump |
Product code: VSU12
Overview
Infrared lamps placed under the tooling plate heat it up. The tooling plate has a square form with dimensions 100x100mm and can be made of any suitable material. It can also be prefabricated with custom openings for fixtures inside it. Tooling plate can be replaced together with the parts on it. This enables serial production. Nitrogen flow blows from the chamber bottom against the tooling plate and thus cools it down. The chamber itself is air cooled.
