Electronic Components We Source
We support the procurement of common electronic components required for PCB assembly. Availability and sourcing options are confirmed according to the manufacturer, part number, package, quantity, and delivery requirements listed in your BOM.
BOM Review
-
Provide your BOM with manufacturer part numbers, descriptions, packages, quantities, and approved alternatives. Our team checks the information before sourcing begins.
Sourcing & Quotation
-
We evaluate available sourcing channels, lead times, order quantities, and pricing before preparing a line-by-line quotation.
Order & Incoming Inspection
-
After approval, purchase orders are placed and delivery progress is monitored. Received components undergo inspection according to the agreed project requirements.
Kitting or Delivery
-
Verified components can be packed for direct shipment or prepared as production kits for use on our SMT and DIP assembly lines.
Incoming Component Inspection
Incoming inspection requirements are selected according to component type, sourcing channel, project risk, and customer specifications.
| Inspection Item | Purpose | Inspection Method |
|---|---|---|
| Part Number Verification | Confirm that components match the approved BOM | Check manufacturer, part number, package, quantity, and purchase records |
| Packaging Inspection | Identify damaged or unsuitable packaging | Inspect reels, trays, tubes, moisture barriers, and protective packaging |
| Label & Lot Review | Support identification and traceability | Review labels, date codes, lot numbers, quantities, and supplier information |
| Visual Inspection | Detect visible damage or abnormal conditions | Inspect pins, leads, surfaces, markings, oxidation, and package condition |
| Dimensional Check | Confirm package and component dimensions | Compare key dimensions with drawings or datasheet information |
| Moisture Sensitivity Review | Support proper handling of sensitive devices | Check packaging condition, moisture indicators, and storage requirements |
| Solderability Evaluation | Assess solder wetting when required | Conduct agreed sampling or solderability testing |
| X-Ray Inspection | Inspect internal structures when necessary | Use X-ray equipment for risk-based or customer-specified inspection |
| Electrical Testing | Verify selected electrical characteristics | Perform agreed sampling tests based on component type and requirements |
| Documentation Review | Maintain procurement and inspection records | Record sourcing, receiving, inspection, and nonconformance information |
Your Trusted PCB Assembly Partner
Whether you're validating a new design or preparing for production, our PCBA service helps you move forward with confidence.
Smarter Component Procurement for Stable Production
We combine sourcing coordination, engineering review, and supply-risk management to help keep your PCB assembly projects on schedule.
Reliable Procurement Beyond Price Comparison
Component sourcing involves more than finding the lowest quotation. Availability, supplier reliability, part condition, traceability, lead time, and compatibility with the PCB design should all be considered. Cheng Jie Da coordinates procurement with engineering and production teams to help customers manage supply risks and keep PCB assembly projects moving.

Frequently Asked Questions
Find answers about BOM sourcing, component availability, alternative parts, inspection, and production kitting.
WWhat information should be included in my BOM?
Please provide the manufacturer part number, component description, package, required quantity, and approved alternative information. Target delivery dates and special quality requirements should also be included when applicable.
What types of electronic components can you source?
We can source common active, passive, electromechanical, connector, sensor, power, and communication components used in PCB assembly. Availability depends on the specified manufacturer, part number, package, quantity, and market conditions.
Can you help source obsolete or hard-to-find components?
Yes. Our team can review available sourcing options and evaluate potential alternative parts. Sourcing feasibility and inspection requirements are confirmed individually because obsolete components may involve higher availability and quality risks.
Can you recommend alternative components?
Yes. Possible alternatives can be compared based on electrical specifications, package, footprint, lifecycle status, availability, and cost. No substitution should be used without customer or authorized engineering approval.
How do you inspect incoming components?
Inspection may include part-number verification, packaging and label checks, visual inspection, quantity confirmation, dimensional review, and additional testing when required. The inspection scope depends on component type and project requirements.
