02Trust layer · the entry ticket

Standards are the entry ticket, not the sales pitch.

12 / 24 ISO 900115 / 24 RoHS15 / 24 CE2 publish none

Of the 24 partner sites, 12 list ISO 9001 among their certifications, 15 list RoHS and 15 list CE, read from each site on 13 September 2026.

01
A close view down one SMT line, with pick-and-place heads and feeder reels in strict alignment
ISO 9001 is a management system It certifies how a site runs, not what it makes. Read the scope sentence, not the badge.
02
A technical scope document beside a board sample on a pale bench under even light
CE is a declaration A manufacturer's declaration of conformity with a technical file. Not a certification and not an approval.
03
A finished autonomous delivery robot with a closed white body and a sensor band
Two sites publish nothing Their cards render proof points instead — patents, model counts, quality gates — never a badge they did not publish.
04
An engineering drawing laid flat beside a scale rule on a pale desk
The class is yours to set IPC puts the product-class decision on the user, so it belongs in your purchase order, not in a brochure.
05
Digital calipers closed around a machined aluminium housing beside a blank inspection checklist
Inspection is the backstop Pre-shipment inspection runs to ISO 2859-1 general inspection level II, with the AQL you agree.
06
A rack battery backup shelf, a supercapacitor module, a CRPS module and a metering unit staged in one row
Third-party labs on request Samples and written reports can go to accredited laboratories for your own confirmation.
