This product is a 2-layer flexible PCB with stiffener for designs that need flexible routing plus reinforced connector or assembly areas. It supports FPC design considerations such as copper thickness range, small hole support, fine trace/space, minimum pitch, copper-to-board-edge clearance, coverlay opening, and coverlay web requirements.
A stiffener is useful when the flexible circuit needs a more rigid zone for connectors, soldering, handling, or mechanical mounting. The flexible area and the stiffened area should be designed together so the board can bend where intended and remain stable where components or connectors are placed.
Stiffener and Flex Area Design
In a 2-layer FPC, the copper routing must work with the bending direction, coverlay design, and connector location. The stiffener should normally be placed only where support is required, not across areas that need repeated bending.
The listed fine feature and coverlay requirements show why FPC drawings should include both electrical data and mechanical details. Copper-to-edge clearance, coverlay openings, and connector pitch can affect whether the flexible PCB is suitable for the final assembly.
Application Fit
This flex board with stiffener is suitable for connector tails, display modules, compact electronics, control assemblies, and products where a flexible circuit needs local reinforcement at soldering or insertion areas.
What to Confirm Before Production
Before production, confirm the FPC layer structure, copper thickness, stiffener material and thickness, adhesive requirement, connector area, bend radius, coverlay opening, pitch, and whether the flex area will be static or dynamic. For assembly-related projects, see turnkey PCB assembly.
Custom FPC with Stiffener Manufacturing
For quotation and manufacturability review, provide Gerber files, drill files, and FPC stack-up drawing, stiffener drawing, bend-area notes, connector drawings, coverlay requirements, surface finish, quantity, and assembly notes. For file preparation questions, see the FAQ on design and technical issues.
