Flexible PCB manufacturers in China
ChinaPCB profiles Chinese flexible PCB factories by the construction they actually publish — polyimide system, coverlay, stiffener and bend requirement — with each claim tagged by evidence level and review date rather than a generic flex label.
Last reviewed: Tue Nov 10. See how evidence levels work.
Two different products that both get called flex
A flexible circuit that is bent once during assembly and a dynamic flex that is bent for the life of the product are not the same qualification. The copper type, coverlay and bend radius all change. We keep these as separate fields on a profile rather than accepting “flex PCB” as a capability statement.
What we check before listing a factory here
- Whether the polyimide system and copper type (rolled annealed or electrodeposited) are named.
- Whether stiffener material and placement are specified for the same series.
- Whether coverlay lamination and laser cutting are done in-house.
- Whether the bend requirement is static or dynamic, and where that is documented.
Factories in this category
No factory has cleared the hard-verification bar for flexible circuits yet. When one does, this section will list its registered legal entity and production address, and keep static-bend and dynamic-bend capability as separate fields rather than a single “flex” claim.
