# PCBELEC

> PCB fabrication and PCB assembly, from prototype to production.

Manufacturing requirements are confirmed for each project. Specify PCB fabrication, PCB assembly (PCBA), or a combined scope. Assembly capabilities and verification are confirmed for each project.

## Manufacturing and engineering
- [PCB manufacturing services](https://www.chinasuqi.com/en/manufacturing/index.md): Explore prototype, quick-turn, low-volume and production PCB fabrication. Choose a service based on your build stage and manufacturing requirements.
- [PCB technologies](https://www.chinasuqi.com/en/pcb-technologies/index.md): Compare rigid, multilayer, HDI, flexible, rigid-flex, metal-core, high-frequency and heavy-copper PCB manufacturing requirements.
- [PCB manufacturing capabilities](https://www.chinasuqi.com/en/capabilities/index.md): Review PCB construction, materials, copper, drilling, surface finish and verification requirements before submitting a manufacturing quotation.
- [PCB materials and stackup requirements](https://www.chinasuqi.com/en/materials/index.md): Explore FR-4, high-Tg, polyimide, high-frequency and metal-based PCB material categories and prepare a clear material specification.
- [Quality management for PCB fabrication](https://www.chinasuqi.com/en/quality/index.md): Understand the quality workflow from engineering and incoming materials through process inspection, final verification and shipment release.
- [Bare PCB testing and inspection](https://www.chinasuqi.com/en/quality/testing/index.md): Explore electrical testing, flying probe, impedance checks, microsection analysis and visual or dimensional inspection for bare PCB orders.
- [PCB manufacturing file checklist](https://www.chinasuqi.com/en/resources/file-preparation/index.md): Check Gerber, drill, stackup and fabrication drawings, then add material, copper, finish, quantity and delivery requirements for a PCB quote.
- [How to order custom PCBs](https://www.chinasuqi.com/en/resources/order-guide/index.md): Follow the PCB order process from file submission and engineering confirmation to approved manufacturing, inspection and delivery arrangements.
- [FR-4 PCB Materials](https://www.chinasuqi.com/en/materials/fr4/index.md): Compare FR-4 laminate requirements for rigid and multilayer PCBs: grade, Tg, dielectric construction, copper and approved substitutions.
- [High-Tg PCB Materials](https://www.chinasuqi.com/en/materials/high-tg/index.md): Understand high-Tg FR-4 selection for thermally demanding PCBs, including assembly exposure, laminate properties and stackup requirements.
- [Polyimide Materials for Flex & Rigid-Flex PCBs](https://www.chinasuqi.com/en/materials/polyimide/index.md): Specify polyimide flex circuits as a complete material system: copper, adhesive, coverlay, stiffeners and the intended bend conditions.
- [Rogers PCB Materials & RF Stackups](https://www.chinasuqi.com/en/materials/rogers/index.md): Define Rogers laminate grade, dielectric thickness, copper and bonding requirements for RF, microwave and hybrid PCB stackups.
- [Controlled Impedance PCB Fabrication](https://www.chinasuqi.com/en/pcb-technologies/controlled-impedance/index.md): Prepare controlled impedance PCB requirements: target values, single-ended or differential structures, reference layers, stackup and TDR verification.
- [PCB DFM & Pre-Production Engineering](https://www.chinasuqi.com/en/resources/dfm-review/index.md): Prepare for PCB design-for-manufacturing review: consistent Gerbers, drill data, stackup, impedance and documented engineering approval.
- [Flying Probe Testing for Bare PCBs](https://www.chinasuqi.com/en/quality/flying-probe-testing/index.md): Understand fixtureless bare-board electrical testing, the opens and shorts it can detect, and how it differs from AOI and functional testing.
- [PCB Manufacturing Process: From Files to Finished Boards](https://www.chinasuqi.com/en/resources/pcb-manufacturing-process/index.md): Follow the PCB fabrication workflow from engineering release through circuit formation, drilling, plating, finishing and agreed inspection.
- [PCB Assembly Services (PCBA)](https://www.chinasuqi.com/en/pcb-assembly/index.md): Discuss PCB assembly with PCBELEC. Prepare your board revision, BOM, component placement information, assembly instructions and required verification.
