Precision FPC Assembly Service — Flex PCB Components

A PCB is a printed circuit board, usually made from rigid materials such as FR4, metal core, ceramic, or other substrates. An FPC is a flexible printed circuit that bends or folds to fit compact or moving applications. FPCs are often used in wearables, medical devices, displays, sensors, and products where space savings, lightweight construction, and dynamic flexibility are important.

PCB assembly turns a bare circuit board into a working electronic assembly by placing and soldering components according to the BOM and design files. The process can include SMT placement, through-hole insertion, reflow or wave soldering, inspection, programming, functional testing, and protective coating. For flex PCB components, careful handling and process control are especially important to prevent material stress.

Yes. FX PCB supports flex PCB manufacturing and assembly workflows, including single-layer and multi-layer flexible circuits, component procurement, SMT/THT assembly, inspection, and testing. The team reviews customer files before production and can help identify manufacturability concerns early, which is especially valuable for flexible circuits with tight spacing, fine-pitch components, or compact mechanical constraints.

For the most accurate quote, provide Gerber files, BOM, centroid or pick-and-place data, assembly drawings, stack-up details, testing requirements, and any coating, packaging, or compliance expectations. If you have alternative approved components, include those as well. Clear documentation helps FX PCB validate manufacturability, source parts efficiently, and provide transparent pricing for fabrication and assembly.

FX PCB uses structured quality controls including DFM review, controlled component sourcing, precision assembly equipment, AOI inspection, X-ray inspection when appropriate, electrical testing, and functional test support. Assembly work can follow IPC-A-610 Class 2/3 standards. The company also maintains ISO9001, ISO14001, ISO13485, UL, RoHS, and REACH-related capabilities for regulated and global-market products.

Turnaround depends on board complexity, component availability, testing requirements, coating needs, and order quantity. FX PCB offers fast-turnaround prototyping, with boards assembled from 24 hours once all parts are available, and quick-turn assembly often within 1–2 weeks. Component shortages or special processes such as Parylene coating may affect the final delivery schedule.

Yes. FX PCB offers component sourcing and procurement support using an experienced sourcing team, bulk buying power, and access to over 600k local stock options. The team can suggest alternative components to reduce cost, shorten purchasing time, or address shortages. Any replacement part must be approved by the customer before it is used in production.

Yes. FX PCB provides protective coating services including conformal coating and Parylene nano-vacuum coating. These coatings can improve resistance to moisture, salt fog, acid, alkali, and harsh operating conditions. Parylene coating is ultra-thin, transparent, and suitable for demanding applications, including medical, military, commercial, and waterproof electronics that require added environmental protection.
