FAQ
Expanded answers for engineers and sourcing. Capacity figures, satisfaction % and founding year are not published until unified.
What is included in LST one-stop on this site?
Five lines: component sourcing, PCB manufacturing, FPC/Rigid-Flex, PCBA and EMS/box-build. You can order one line or a bundle. Plastic injection is not featured among the five primary lines.
What should I send for a quote?
BOM (Excel) with Supplier/Part#, positions, description and package; Gerber RS-274X; for assembly — silkscreen/copper/stencil layers; quantity; kitting mode. Stack-up and brand restrictions optional. Please email files to [email protected].
Do you make military products?
The group holds military qualification certificates and production permits; we do not display them on this site. Publicly we discuss civilian avionics and industrial/RF electronics — without a military-marketing showcase.
Why are there no certificates in the header?
We avoid unverified or outdated certificate wording from mirror sites. The Quality page lists system names (ISO 9001, IATF 16949, UL, ISO 13485) as text only — no scans. Certificates are intentionally absent from the homepage.
Where is production?
Public sites: Shenzhen, Suining (PCB), Kunshan (FPC), Vietnam Bac Giang.
How are the four footer sites related?
These are public group sites: Greathome, Leadsintec Group, made-in-pcb and leadsintec.com. Links open in a new tab.
Do you have an office in Moscow?
Yes. We also have an SMT production line in Moscow.
What contact channels for Russia?
Alexander Yan: Email [email protected], Telegram +79164442443. The quote form on this page accepts the inquiry in the UI; please email files.
Do you promise free DFM and a 24-hour reply?
We do not publish a fixed SLA or ‘free within N hours’. Engineering file review is scoped per project.
