Flexible PCBs

Dual access copper connections are an innovative technique for the creation of single-sided FPCs (flexible printed circuits), which however also require a connection on the other side. Thanks to the dual access copper technique developed by Silga it is possible to directly connect the tracks of a single-sided FPC to a support, safely and effectively. The advantages? Among all the possibility of avoiding the use of nickel tabs for the connection; in fact, the dual access copper technique guarantees direct contact and consequently greater robustness by virtue of the fact that additional welding is not required (critical aspect of the robustness of the products, also linked to the stress generated by dimensional variations), which is instead necessary for nickel tab. Furthermore, in the case of connection to battery packs, based on customer needs in terms of materials used in the busbars and the type of welding

Lightweighting, freedom of design and cost reduction are the drivers for every application and sector. For this reason, Silga is increasingly called upon by its Customers to become a partner in the development of solutions that achieve this objective. Especially if they are non-standard solutions. One of the most important and successful is that of FLEXIBLE HEATERS . In this area, in fact, skills related to: Flexible PCB's Alternative materials Chemical etching capability of metals other than copper Know How in using functional inks Exclusive surface finishes developed by Silga. Production lines adequate for the required volumes

FPCs solutions for batteries include Flexible Heaters , an innovative technology developed for the thermal management system of the batteries; in this way, the performance of the battery is improved, prolonging its life, especially when it is located in areas with extreme climatic conditions. Flexible heaters can be made using the traditional technique or the new Printed Electronics technology , with the possibility of also using PTC inks for automatic temperature regulation. Furthermore, the “Made in Silga” Flexible Heaters offer the possibility of integrating special finishes to guarantee excellent performance in any working condition.

Silga designs and creates new applications of high-performance circuits for the automotive sector in the field of e-mobility, such as Gigaflex , flexible printed circuits for batteries , intelligent solutions for sensor-controlled connections of battery cells and systems for connecting modules to the BMS . This solution allows for a drastic reduction in the size of battery connection systems, eliminating any cumbersome wiring. In this way, flexible printed circuit boards for batteries become the perfect mix between connectivity , performance and lightness .
