Question 1

What is your company background and core business?

Accepted Answer

We are Shenzhen Tianditong Electronics Co., Ltd (tdt-ele), established in 2004 with over 20 years of experience in PCB and PCBA manufacturing. We provide one-stop services from PCB fabrication to full product assembly, including SMT, DIP, IC programming, functional testing, conformal coating, potting, and box build assembly.

Question 2

What certifications does your factory hold?

Accepted Answer

We are certified with IATF16949 (automotive), ISO9001:2015, ISO13485 (medical devices), QC080000 (hazardous substance management), ISO45001 (occupational health & safety), and Apple MFI certification. These certifications ensure quality and compliance across various industries.

Question 3

What files do you need for a quotation?

Accepted Answer

For an accurate quotation, please send us your Gerber files (PCB layout) and Bill of Materials (BOM). We also recommend including any special requirements such as material preferences, testing specifications, or delivery timelines. We will reply within 24 hours on business days.

Question 4

Do you support prototype and small-batch production?

Accepted Answer

Yes, we support all volumes from prototypes and small batches to high-volume mass production. Our flexible production lines and ERP/MES system allow us to handle quick-turn prototypes (as fast as 48 hours for PCBs) and scale up efficiently.

Question 5

What inspection and testing capabilities do you offer?

Accepted Answer

We utilize SPI (Solder Paste Inspection), X-RAY for BGA/QFN inspection, AOI (Automated Optical Inspection) for soldering quality, ICT (In-Circuit Test) for component-level testing, and functional testing for final assembly. These processes ensure high yield and reliability.

Question 6

What is your typical lead time for PCBA orders?

Accepted Answer

Lead time depends on order complexity and quantity. For standard PCBAs, prototype samples usually take 12 to 15 working days, and production orders take 20 to 25 working days. Urgent orders can be arranged upon request. We track all orders via our ERP and MES systems.

Question 7

Do you offer conformal coating and potting services?

Accepted Answer

Yes, we provide conformal coating (acrylic, silicone, urethane, etc.) to protect PCBs from moisture and contaminants, as well as potting services for enhanced mechanical and environmental protection. These are available as part of our turnkey assembly.

Question 8

What quality control system do you use?

Accepted Answer

We operate a closed-loop quality management system integrated with IATF16949 standards. Our ERP and MES systems trace every batch from incoming material inspection to final shipment. Real-time data collection, SPC analysis, and corrective action procedures ensure consistent quality.

Question 9

Do you support customer-supplied components or full turnkey service?

Accepted Answer

Both options are available. For turnkey service, we source all components from our qualified supplier list. For consignment, you provide the components, and we handle the assembly and testing. We recommend full turnkey for better cost control and supply chain management.

Question 10

How can I get a quick response or send my inquiry?

Accepted Answer

You can email your Gerber files and BOM to our sales team  if desired or contact Tiffany (0086-15889457599) directly. We typically respond within a few hours during working days. We are located in Shenzhen, China, and welcome factory visits.

Question 11

What payment terms do you accept?

Question 12

Do you offer NDA or IP protection for customer designs?

Accepted Answer

Yes, we sign a Non-Disclosure Agreement (NDA) before project start. All customer design files, Gerber files, and BOMs are stored securely in our encrypted ERP system and are never shared with third parties.

Question 13

What PCB materials and surface finishes do you support?

Accepted Answer

We support FR-4, high-Tg, aluminum, flexible PCB, Rogers, and more. Surface finishes include HASL, ENIG, OSP, immersion silver, and immersion tin. We recommend ENIG for fine-pitch components and BGA.

Question 14

Do you provide after-sales support and warranty?

Accepted Answer

Yes, we offer a standard 12-month warranty for all PCBA products. If any defect occurs due to our manufacturing or materials, we will rework or replace the product at no cost.

Question 15

What is the minimum order quantity (MOQ) for PCBA orders?

Accepted Answer

We have no strict MOQ. We accept orders from 5 piece for prototypes to millions for mass production. but we welcome small batch inquiries as well.
