After the opening of a second 100% automated SMT line, we are opening a selective brazing line for through-holes with the acquisition of a Ersa model Ecoselect 4 selective wave machine.
The electronic board prototype manufacturing process differs from the series assembly. After having invested in a Jetting machine more adapted to the production of small series, we make the choice to invest in a selective wave machine for the soldering of through hole components. The goal remains the same: to assemble boards as quickly as possible with industrial quality.
How does a selective wave work?
The principle is to solder through hole components from below the board. A molten tin nozzle that moves beneath the board, deposits alloy directly on the pins of the component. The conveniences of this technique are :
Process steps
Technical constraints to be respected
The selective wave is used in industrial production for large series, it imposes some constraints to respect :
We remain faithful to our objectives: to make small series of industrial quality. This investment completes the first one industrial chain specifically dedicated to the prototyping of electronic boards.
