Send us your layout or concept, and our senior engineers will review your files for manufacturability, improving your design before it hits the production line. - PCB Fabrication – Single-layer, multi-layer, HDI, aluminum-based, or ceramic—we fabricate PCBs of all complexities. Our in-house plant supports quick turnarounds and strict quality control for every batch. - PCB Prototype – Need your prototype in 24–72 hours? We’ve got your back. Ideal for engineers in the development phase, we offer fast PCB prototyping with full traceability, fly-probe testing, and surface finish options. - PCB Assembly – Our turnkey PCB assembly service covers everything from component sourcing, SMT/DIP soldering, to functional testing. You send us your BOM and Gerber—we handle the rest. - Components Sourcing – Reliable sourcing of original, competitive prices, traceable electronic components. - IC Programming – Pre-programming and testing of integrated circuits to streamline your assembly process. ## What PCB Types Does EBest Circuit (Best Technology) Manufactured? We are capable of manufacturing a wide variety of PCB types, including but not limited to: - FR4 PCBs (high speed PCB, IC substrate, high TG PCB, extra thin PCB, our special semi-rigid flex PCB and so on.) - Metal Core MCPCBs (aluminum based PCB, copper clad PCB, sinkpad PCB, thermoelectric copper separate PCB) - Ceramic PCBs (AlN, BeO, Al₂O₃, Zro2) - Flexible and Rigid-Flex PCBs, FFC, Dual access PCB - HDI PCBs - High-Frequency PCBs - Heavy Copper PCBs - Busbar PCBs - Hybrid Substrate PCBs [https://www.bestpcbs.com/blog/wp-content/uploads/2025/04/D7F17AF8-991C-4767-AFE5-3580B3B25E35.png](https://www.bestpcbs.com/blog/wp-content/uploads/2025/04/D7F17AF8-991C-4767-AFE5-3580B3B25E35.png) Whether you need high-reliability boards for aerospace, thermally conductive boards for LEDs, or RF boards for communication devices, we have the capability to deliver. ## PCB Prototype Lead Time We understand how crucial speed is in product development. Our **[standard PCB prototype](https://www.bestpcbs.com/blog/2025/04/pcb-fabrication-manufacturer-prototype-design-and-assembly/) **lead time is: - Single-layer & double-layer PCBs: as fast as 24 hours - 4-layer PCBs: typically 48–72 hours - 6-layer or above: around 3–5 working days, depending on complexity Below is a detailed prototype lead time sheet at EBest Circuit (Best Technology), the expedited options are available to meet urgent project deadlines. **Prototype(<1m²) ** **Layers   ** **Normal Service   ** **Expedited Service**       FR4 PCB 1 Layer 3-4 days 24 hours 2 Layers 4-6 days 24 hours 4 Layers 8-10 days 48 hours 6 Layers 8-10 days 72 hours 8 Layers 10~14 days 72-96 hours 10 Layers 14-18 days 72-96 hours HDI (1+N+1 2+N+2) 2.5 – 3.5weeks TBD (depend on design) ## EBest Circuit (Best Technology)’s PCB Assembly Capabilities And as a one-stop service provider to customers, we offer [PCB assembly service](https://www.bestpcbs.com/products/pcba.htm) as well, such as: - SMT (Surface-Mount Technology) - DIP (Dual In-line Package) - Reflow Soldering (for SMD components) - Wave Soldering (for DIP components) - Hand Soldering (connectors, through hole components) - Mixed Assembly Technologies - Wire Harness Assembly - PCBA Testing - Box Building Assembly [https://www.bestpcbs.com/blog/wp-content/uploads/2025/04/smt-factory.jpg](https://www.bestpcbs.com/blog/wp-content/uploads/2025/04/smt-factory.jpg) ## How to Work with us – From File to Finished Board? **Step 1: Upload Your Files** Submit your Gerber, BOM, or PCB design files via our secure portal. We support various formats and guarantee file confidentiality. **Step 2: Engineering Review & Instant Quote** Our team performs a [DFM check](https://www.bestpcbs.com/blog/2025/04/free-design-for-manufacturing-dfm-support-dfm-vs-dfma/) and confirms design compatibility. You’ll receive a quote and estimated lead time within 2 hours. **Step 3: PCB Fabrication & Parts Procurement** We begin board production and source parts simultaneously through authorized channels like Mouser, DigiKey, and Arrow. **Step 4: SMT/DIP Assembly & Testing** Boards are assembled in our SMT lines with 3D AOI, X-ray, and functional testing to ensure performance and soldering quality. **Step 5: Secure Packaging & Global Shipping** We pack your PCBs using anti-static materials and ship via DHL, FedEx, or your chosen method. Worldwide delivery in 3–5 days. ## Custom PCB Board Quote Not sure about all your PCB specs? No problem — we’re here to help.
