Mabaka a mang a kang ho rarahana ha boto, kaho e tenyetsehang khahlanong le e thata, likhetho tsa ho qeta holim'a bokaholimo , le linako tsa ho etella pele le tsona li susumetsa litheko, ka li-premium tse tlohang ho 0-150% ho latela thepa, qetello le potlako. Mohlala, liboto tse tenyetsehang li bitsa chelete e ngata ka lebaka la liphapang tsa thepa le ts'ebetso, 'me liphetho tsa bokaholimo tse kang ENIG kapa khauta li tla le melemo e eketsehileng ea ts'ebetso.

Maano a ho ntlafatsa litšenyehelo a kenyelletsa litokiso tsa moralo, joalo ka ho leka-lekanya botenya ho isa ho 1.6mm le ho fokotsa palo ea lera. Ho kopanya meralo e mengata ka tatellano e le 'ngoe ho ka theola litheko, joalo ka ho rera liodara tsa selemo le selemo bakeng sa litheko tse betere. Ho leka-lekanya lintlha ka ho fokotsa mamello le ho sebelisa thepa e tloaelehileng ho fokotsa litšenyehelo tse sa hlokahaleng, ha ho laola linako tsa ho etella pele ho thusa ho qoba litefello tse potlakileng. Litsenyehelo tsohle tsa botho (TCO) li bonts'a ROI ho tsoa ho li-PCB tse mosehla ka taolo ea boleng bo potlakileng, bofokoli bo fokolang, le litefiso tse tlase tsa ho sebetsa hape. Li-PCB tse mosehla li ka fana ka boleng ba bohlokoa, 'me ROI e ile ea hlokomela kapele ka lihlopha tse kholo le ho fana ka phaello ea boleng ba brand le khotsofalo ea bareki.
