Before you write.
How fast will someone reply?
Inside 24–48 hours, from a human on the engineering desk — not an autoresponder. If the BOM is complete, the reply is a quote with DFM findings attached.
What should an RFQ include?
BOM with refdes and MPN, board data in Gerber or EDA format, target quantity, destination country and Incoterms, and any certifications your market requires. The fuller the packet, the sharper the first quote.
Can we see the factory before awarding?
Yes — visits to the Bao'an campus run by appointment through your program manager. For teams further out, we can walk the same lines on a scheduled video audit.
Which legal entity do we contract with?
Shenzhen Piesia Electronic Technology Co., Ltd. — EMS-Trade is the brand and the operating network behind the contract. Quote, order and invoice all carry the same legal name.
Prefer email?
Write to the desk directly — including attachments, so the engineering review can start on the first reply.
