Company Profile

FAQ

Q1:If I make an order PCB+Assembly, can I send components to Tdt-ele directly? (Consigned Parts)?
A: Tdt-ele offers consigned component services (customer-provided ), in addition to turnkey PCBA solutions. This suits hard-to-source or long-lead-time parts, but customers bear freight, customs fees, and clearance responsibilities. Tdt-ele assumes no liability for transit issues (seizure, damage, loss) or delays from pending parts.
 
Unfamiliarity with regional customs or inadequate part preparation may cause costly delays. Thus, we strongly recommend avoiding consigned parts unless necessary. For hard-to-source components, first explore alternatives (substitute parts or alternative suppliers).
 
Q2:What is the PCBA Delivery Time?
A: Our production timeline includes PCB manufacturing, material procurement, and assembly, with the goal of meeting customer needs as quickly as possible. If components have long lead times, procurement (PCB + components sourcing) may take 7–20 days, resulting in a standard production cycle of 25–30 days
 
Q3:How can I request a quote from tdt-ele?
A: To receive a quote, please send your Gerber and BOM files to your dedicated sales representative. If you are a new customer, kindly submit your inquiry to Tiffany, and Tiffany will respond within 8 hours
 
Q4:What quality standards do you follow?
A: Tdt-ele complies with IPC-A-600 (for PCBs) and IPC-A-610 (for PCBAs). If you have additional requirements, please specify them in your inquiry
 
Q5:What testing procedures do you perform for PCBs and PCBAs?
A: For PCB:
Visual Inspection
Electrical Testing
AOI (Automated Optical Inspection)
Microsection Analysis
Solderability Test
Thermal Shock Testing
Impedance Test
