In the scope of electronic production, ERNI assembles PCBs with cutting-edge technology. Various solder technology with lead-free or lead solder and pressfit technologies are used, which are perfectly tailored to the requirements of the system. ERNI inspects every produced assembly with comprehensive testing. Specialists develop and create their own test software and test adapters jointly with the customer.

PCB assembly is done via SMT (Surface Mount Technology), via THT wave soldering or via THR reflow soldering. During assembly, modern assembly lines, template printers and Pick & Place automatic systems with high assembly capacity are used. High performance reflow and wave soldering systems with nitrogen atmosphere are available for solder processes. The mounting of assemblies is done on semi-automated assembly stations.
In assembly plating ERNI uses processes such as selective thin film coating, selective thick film coating or fluoropolymer coating, depending on requirements. On request ERNI assumes complete material procurement for all EMS partial processes.
