Online Prototype & Production Substrates
Explore high-density multi-layer, rigid-flex, RF, and metal-core circuit boards ready for online quoting, automated DFM checks, and high-speed SMT assembly.
The Paradigm Shift in Online PCB Assembly & Turnkey EMS
Moving past fragmented broker chains to algorithm-driven, factory-direct digital manufacturing that cuts product introduction cycles from quarters to days.
Algorithmic Quoting & DFM
Modern online PCB assembly companies bypass the 48-hour email quoting bottleneck. Intelligent cloud engines parse Gerber, ODB++, and BOM files simultaneously, verifying component footprints against SMT feeder rules and flagging thermal clearance traps in seconds.
Unified Accountability
Splitting bare-board fab, component brokers, and assembly houses introduces finger-pointing when solderability issues or tombstoning occur. Turnkey online providers manage substrate fabrication, authentic BOM purchasing, SMT mounting, and box build under a single warranty.
Agile NPI & Mass Ramp
New Product Introduction (NPI) demands rapid iterative agility. With dedicated prototype lines linked with automated high-speed SMT mass-production systems, designs transition seamlessly from 5-piece verification batches to 100,000-piece commercial rollouts without requalification.

Comprehensive PCB Assembly Pricelist & Cost Estimation Framework
Demystifying electronics manufacturing line items. Understand the exact mathematical formulas, setup variables, and volume discount tiers that dictate your project's bottom line.
The Anatomy of PCBA Quoting
Unlike raw commodities, PCBA pricing is a synthesized formula covering engineering overhead, raw laminate square inches, component procurement cost margins, SMT point counts, stencil laser etching, and functional testing time.
Cost = Bare_PCB + SMT_Setup(NRE) + (Points × C_joint) + BOM_Cost(1 + Scrap_Rate) + Stencil_Tooling + Testing_Hourly
Key Cost Drivers to Optimize
Design choices substantially dictate assembly pricing. Selecting standard 0402 over 01005 passives reduces placement inspection surcharges. Keeping copper weights to 1oz or 2oz avoids custom etching bath setups, and panelizing boards for automated conveyor travel lowers per-unit labor costs.

Frequently Asked Questions: PCB Assembly Online & Cost Control
Crucial commercial and engineering insights to clarify minimum quantities, file requirements, quality assurances, and shipping logistics.
Online PCBA quotes combine setup overhead (SMT programming, laser cut framed stencils, feeder loading) with variable material costs (bare PCB fabrication plus BOM component costs) and placement point count fees. Prototype runs typically carry a flat setup NRE ($30–$80) that absorbs line recalibration, while high-volume runs transition to fractional cent per-joint pricing.
Engineers must supply: 1) RS-274X Gerber or ODB++ files defining copper, mask, legend, and drill layers; 2) Bill of Materials (BOM) in Excel/CSV format indicating reference designators, manufacturer part numbers (MPN), descriptions, and package footprints; 3) Centroid (Pick & Place / XYRS) file with rotation angles; and 4) Assembly drawings specifying unique requirements like conformal coating or selective soldering.
We purchase exclusively through franchised, factory-authorized distributors (including Digi-Key, Mouser, Arrow, Avnet, and direct brand tier-1 channels for TI, ST, ADI, and Microchip). Our Incoming Quality Control (IQC) station conducts pin oxidation inspection, date code validation, tape packaging verification, and decapsulation spectrometry audits whenever open-market allocation parts are unavoidable.
Yes. Our Shenzhen production floor integrates 6 SMT lines and 4 dedicated DIP through-hole lines. We mount micro 01005 passives, ultra-fine 0.35mm pitch BGAs, and dual-row QFNs on automated pick-and-place lines, followed by selective wave soldering or robotic manual soldering stations for high-current terminal blocks and transformers.
Quick-turn bare boards can be fabricated in 24 to 48 hours. When BOM parts are readily available in stock, turnkey assembled prototypes are assembled, inspected via 3D AOI and X-Ray, and dispatched via DHL/FedEx air express in 3 to 9 business days. Standard volume production runs generally complete within 2 to 3 weeks depending on custom parts.
Beyond standard 3D Solder Paste Inspection (SPI) and Automated Optical Inspection (AOI), we construct custom Functional Circuit Testing (FCT) jigs to program firmware, verify voltages, and test digital/analog I/O. For high-reliability sectors, we perform In-Circuit Testing (ICT), continuous thermal burn-in cycling, and environmental stress screening.
Yes. Beyond board manufacturing, PCB ADEPT coordinates CNC metal milling, plastic injection molding, wire harness crimping, keypad integration, display bonding, potting, retail package design, and dropshipping worldwide directly from our Bao'an facility.
We provide signed, enforceable Non-Disclosure Agreements (NDA) prior to receiving design data. Project documentation is stored on encrypted, access-restricted internal servers. Firmware binaries are strictly transferred to designated programmers via secure tokens, preventing reverse engineering or unauthorized proliferation.
