Essential files for PCB fabrication and assembly.
Gerber Files
PCB fabrication data including copper layers, solder mask, silkscreen, and board outline.
Bill of Materials (BOM)
Component list with part numbers, quantities, specifications, and approved alternatives where available.
Pick & Place File
Component coordinates, rotation, and placement information for SMT assembly.
Assembly Drawing
Reference drawings showing component orientation and special assembly requirements.
Project Information
Additional details to help us provide an accurate quote.
Testing Requirements
Functional test instructions, test points, fixtures, or acceptance criteria where required.
Production Quantity
Prototype, pilot-run, and expected production quantities to help plan materials and assembly.
Special Requirements
Programming, labeling, packaging, or other project-specific requirements where applicable.
Files not complete yet?
Send us what you currently have. We can review the available information and identify what may still be needed before quotation or production.
Our PCB Assembly Process
A controlled PCB assembly workflow from project review and material preparation to assembly, inspection, testing, and final handoff.
Project Review & DFM
Review Gerber files, BOM, placement data, assembly drawings, quantities, and special requirements before production.
Material Preparation
Coordinate PCB fabrication and component sourcing, verify incoming materials, and prepare parts for production.
SMT Assembly
Apply solder paste, place surface-mount components, and complete controlled reflow soldering according to approved production data.
THT & Secondary Assembly
Complete through-hole insertion, connector installation, manual soldering, and required secondary operations.
Inspection & Testing
Inspect assembled boards and perform required testing according to project specifications before release.
Final Review & Handoff
Complete final review, documentation, packaging, and prepare the PCBA for shipment or further product integration.
From Prototype to Repeat Production
The same controlled workflow supports early builds, pilot runs, and repeat production with consistent process control.
PCB Inspection & Testing
Inspection and testing are integrated into the PCB assembly process to identify assembly issues, verify workmanship, and support project-specific quality requirements.
Quality Throughout PCB Assembly
Quality control is introduced at appropriate stages of material preparation, assembly, inspection, and testing rather than being limited to final inspection.
Assembly Workmanship
Check soldering, component placement, polarity, and connector installation.
Project-Specific Checks
Inspection and testing are applied according to customer documentation and product requirements.
Coordinated Review
Inspection and test information can be coordinated with project documentation where required.
Visual Inspection
Check component orientation, polarity, solder joints, connector installation, and visible assembly defects.
PCB Inspection
Inspect component placement and soldering quality using applicable inspection methods based on project requirements.
Functional Testing
Perform project-specific functional verification using supplied procedures, fixtures, test points, or acceptance criteria where required.
Final Verification
Confirm assembly condition, test status, documentation, and readiness before shipment or further product integration.
Quality Control Across the Process
From PCB Assembly to Complete Product Integration
CINDY MOULD integrates PCB assembly, plastic enclosures, modules, testing, and final assembly in one coordinated workflow.
Integrated Manufacturing Capabilities
Tooling & DFM
Review enclosure structure, PCB fit, connector positions, screw bosses, clips, and assembly clearances.
Plastic Enclosure Manufacturing
Build injection molds and produce custom plastic housings, covers, brackets, and structural parts.
PCBA Preparation
Confirm tested boards, firmware, connectors, interfaces, and assembly requirements before integration.
Module & Product Integration
Install cable harnesses, displays, sensors, switches, modules, and PCBAs into the enclosure.
Product-Level Verification
Check fit, wiring, power-up, controls, interfaces, display response, and required functions.
Final Assembly & Packaging
Complete labeling, accessories, appearance checks, packaging, and shipment preparation.
Engineering Coordination Before Assembly
