Why us

Why buyers come to the group

One contact at the door — then the request goes to the right company and its official workflow.

Four clear contours

RF/microwave, EMS, automation and excess/shortage are separated by company — you see where the RFQ belongs.

Official domains

Catalogs, docs and commercial RFQs live on ttf-svch.com, lst-pcba.com, vwu-ia.com and lot-excess.com — not on this portal.

RU+ focus

Priority on Russia and emerging markets: a clear entry, Russian-speaking contact, routing by direction.

About the portal

Corporate entry — not a catalog

This site is the group map. Product SEO, datasheets and commercial RFQs remain on company domains.
