Today’s stencil printers have evolved into multi-function devices that also perform dispensing and inspection tasks. Process control and traceability connections are also offered, because the complexity of current electronic products demands better production processes.

By Baishakhi Dutta

The production of electronics products requires processes and equipment to be tuned in the most accurate way possible. It also demands the complete attention of operating personnel. Only a perfectly tuned system will deliver the necessary quality at minimum costs. There are also numerous processes and systems to be supported along the production line. It is almost impossible for systems operators to be familiar with all of these, down to the last detail. Clear and unambiguous communication between the operator and the system is thus very important, and easy-to-operate systems are essential. In this article, we have featured some of the latest stencil and screen printer systems that are available in the market.

A few of the latest products available

Model: X5L; Manufacturer: Inotis Co. Ltd
This fully automated high-speed printer has motorised three-stage conveyor systems that ensure a shorter waiting period for the PCB transfer. The model has a multi-point PCB clamping block which provides edge clamping control for board holding in order to obtain the best printing quality for fine pitch devices. It also has a PCB push-down unit, which is used for large-sized PCBs, to prevent warping.
