SMD Assembly

Surface Mounting Device

Casteltech is equipped with three SMD production lines, the first oriented towards medium-high volume production, the second more focused on small to medium volumes with high flexibility and technological sophistication with the possibility of electrical testing before assembly. The latest line purchased allows solder paste to be dispensed directly onto the board and components to be assembled immediately afterwards, without the need for screen printing foil.


The high performance of the oven (8 + 8 + 2 zones) allows to completely absorb the needs of the two assembly lines.

Production is supported by intelligent (Essegi Automation) humidity-controlled cabinets for component management and an AOI for automatic optical inspection of the boards produced.

The production process is completely traced by specialized software with control of the processing phases and production progress.

Casteltech also has a re-work machine (for BGA and QFN) for the repair of defective cards.
