Tonse tikudziwa kuti pali masinthidwe amakalasi amalonda ndi mafakitale. Zosintha zamakalasi amalonda nthawi zambiri zimagwiritsidwa ntchito m'nyumba, mabizinesi ang'onoang'ono ndi malo ena. Zosintha zamafakitale nthawi zambiri zimagwiritsidwa ntchito m'malo ogulitsa. Chifukwa chake, chifukwa chiyani masinthidwe amakalasi sangagwiritsidwe ntchito m'malo ogulitsa? Chifukwa chiyani tikuyenera kugwiritsa ntchito ma switch network ma ring network m'malo ogulitsa?

Choyamba, ntchito zosinthira deta zamasinthidwe amagulu a mafakitale ndi masinthidwe amalonda ndizofanana. Komabe, ponena za mapangidwe ndi kusankha chigawo, mphamvu ndi kugwiritsidwa ntchito kwa zinthu zosinthika za mafakitale zimatha kukwaniritsa zosowa za malo a mafakitale.Kuonjezera apo, kusintha kwa mafakitale kumakhala kosavuta kusiyana ndi kusintha kwamagulu amalonda potengera kukula kwa gawo: Pali madoko osiyanasiyana opangira magetsi ndi madoko amagetsi osankhidwa. Ikhoza kukwaniritsa zofunikira za malo ogulitsa mafakitale posankha zinthu, mphamvu za mankhwala, kugwiritsidwa ntchito, nthawi yeniyeni, kugwirizana, kudalirika, kusagwirizana ndi kusokoneza komanso chitetezo chamkati. Kachiwiri, mawonekedwe osinthira magiredi amafakitale nthawi zambiri amakwaniritsa zofunikira za kapangidwe kake: kapangidwe ka kutentha kwa mafakitale, kapangidwe ka 4-level electromagnetic compatibility design, ndikuwonjezera mphamvu ya AC ndi DC. Kuphatikiza apo, matabwa a PCB nthawi zambiri amathandizidwa ndi "zopewera zitatu".
