Steel Stiffener FPCB

Useing steel stiffeners in PCBs improves mechanical stability, which enhances component support, and ensures the overall durability and reliability of the circuit board in demanding applications.

Two main metal stiffeners are aluminum and stainless steel, but customization is more expensive. Metal stiffeners are therefore significantly more expensive and have longer turnaround times than polyimide and FR- 4 rigiders. The design calls for more component area support than an equivalent thickness FR4 stiffener can offer, despite the fact that stainless steel and aluminum are frequently used for heat dissipation in very small spaces. drilling, milling, registration, and pre-stack prepreg are all necessary steps in the aluminum stiffener bonding process. Drilling, laser cutting, registration, and pre-stack preparation are necessary for the stainless steel stiffener bonding process.

As following common thickness of core for client to choice then to suit your design.

As a result, Stiffeners typically press to both sides of a flex PCB in designs, but occasionally this requires multiple lamination cycles, which raises the cost and lead time. Additionally, stiffeners must be precisely and completely defined in the Gerber file set, and the mechanical layers for the top and bottom layers should be distinct.
