A dzenje conical amene kudula kulola lathyathyathya mutu wononga kuti ntchito amatchedwa dzenje countersink. Angagwiritsidwenso otchedwa monga dzenje conical kuti Kadulidwa mu PCB laminate, kapena dzenje analengedwa ndi ntchito kubowola. Cholinga ndi kupereka mwai mutu wa wononga countersunk, ikapita anaikapo ndipo tili m'mavuto pansi mu dzenje, kukhala chamadzi ndi padziko laminate lapansi. Chulucho zooneka dzenje, amene kudula mu PCB laminate, ndi countersink. Aliyense ntchito kulola mutu tapered a wononga akhale chamadzi ndi pamwamba kapena pansi laminate lapansi.

Ndi zimagwiritsa ntchito, kotero kuti lathyathyathya mutu wononga akhoza kukhala chamadzi ndi padziko ndikuona woyera ndi unsembe. Kuonetsetsa kapangidwe oyenera kupanga, opanga ambiri amafuna mfundo za m'mimba mwake dzenje. Ayeneranso kudziwa ngati dzenje ndi yokutidwa kapena ayi. Kudziwa ngati dzenje ndi mbale kapena yovuta kwambiri chifukwa chakuti zinthu zina dzenje unplated akhoza kukupatsani kwa chimango, amene chingachititse vuto lomwe lingafune plating kukonza. Countersinks kawirikawiri 82 digiri kapena 90 degree; Komabe, angelo ena n'zotheka kuti makasitomala kuti ayenera kupereka kwa PCB fabricator.

Pakuti pobowola molondola mabowo countersink, mfundo zotsatirazi chofunika:

▪ Kodi ndi mbali ya bolodi ndi dzenje countersink ayenera mokhomerera, pamwamba kapena pansi?

▪ Kodi lakuya ndi kutsinde kudzera mwa yokutidwa kapena osakhala yokutidwa?

▪ Taper ngodya kapena countersink ngodya

▪ Countersink awiri

▪ The yomalizidwa awiri a kutsinde mdzenje

▪ Kuya kwa countersink ndi kuti mokhomerera

M'munsimu fanizo limene chitsanzo cha dzenje countersink:

A: Countersink njingayo, D: Countersink awiri, D: dzenje awiri, H: dzenje kuya
