Pankhani ya kulephera kwa PCB, ndi njira ndi zida zotani zomwe zilipo kuti zizindikire?

1. Common PCB dera zolephereka gulu makamaka anaikira pa zigawo zikuluzikulu, monga capacitors, resistors, inductors, diode, triodes, munda zotsatira transistors, etc. The Integrated chips ndi crystal oscillators mwachionekere kuonongeka, ndipo ndi mwanzeru kuweruza kulephera. mwa zigawozi Ikhoza kuwonedwa ndi maso.Pali zizindikiro zoyaka zoonekeratu pamwamba pa zipangizo zamagetsi ndi zowonongeka zoonekeratu.Zolephera zotere zitha kuthetsedwa mwa kusintha mwachindunji zigawo zamavuto ndi zatsopano.

2. Sikuti kuwonongeka konse kwa zida zamagetsi kumatha kuwonedwa ndi maso, ndipo zida zowunikira akatswiri ndizofunikira pakukonza.Zida zowunikira zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo: multimeter, capacitance mita, etc. Zikadziwika kuti voteji kapena zamakono za chigawo chamagetsi sizili mkati mwazonse, zikutanthauza kuti pali vuto ndi chigawocho kapena gawo lapitalo.Bwezerani ndikuwona ngati zili bwino.

3. Nthawi zina tikamapereka zigawo pa bolodi la PCB, tidzakumana ndi vuto lomwe silingadziwike, koma gulu ladera silingagwire ntchito bwino.M'malo mwake, mukakumana ndi izi, nthawi zambiri zimakhala chifukwa chogwirizana ndi magawo osiyanasiyana panthawi yoyika kuti ntchitoyo ikhale yosakhazikika;mutha kuyesa kuweruza momwe vutolo lingathere potengera mphamvu yapano ndi mphamvu yamagetsi, ndikuchepetsa malo olakwika; ndiye yesani kusintha gawo lomwe mukukayikira mpaka vutolo litapezeka.
