A gomba conical iyo unotemwa kubvumira sandara musoro sikuruwa kushandiswa inonzi countersink buri. Rinogonawo kunzi ave conical buri kuti unotemwa kuva pcb laminate, kana buri akasikwa pachishandiswa chibooreso. Chinangwa chikuru ndechokudzibatsira kutendera musoro countersunk sikuruu, kamwe iri akaisa uye Volt pasi mugomba, kuti ugare chomumba pamwe pose laminate. The cône zvakaumbwa buri, riri racherwa pcb laminate, ane countersink. Vazhinji kushandiswa kubvumidza tapered musoro sikuruwa kugara chomumba pamwe kumusoro kana pasi laminate.

Zvinonzi ainyanya kushandiswa, saka kuti sandara musoro sikuruwa anogona kugara chomumba pamwe pose kuti yakachena Kutarira uye kugadzwa. Kuti pave nechokwadi yakarurama magadzirirwo mukugadzira, vagadziri vakawanda zvinoda nezvokuzadziswa mugomba dhayamita. Vanofanirawo kuziva kana mugomba iri kuifukidza kana kwete. Kuziva kana mugomba iri ndiro kana kwete vachishoropodza nokuti mamwe mamiriro ezvinhu ane unplated gomba inogona makateyiwa kune urongwa, izvo zvinogona kukonzera dambudziko kuti zvaizoda yakanamirwa pamifananidzo kugadzirisa. Countersinks kazhinji vane 82 dhigirii kana 90 dhigirii angled; Zvisinei, dzimwe pamakona zvinogoneka kuti mutengi raizofanira kupa kune pcb fabricator.

Nokuti Drilling yakarurama countersink mumakomba, zvinotevera mashoko chinodiwa:

▪ Nderipi divi bhodhi ndiwo countersink buri zvinofanira akachera, pamusoro kana pasi?

▪ Ko singi uye mugodhi kuva kuburikidza kuifukidza kana vasiri kuifukidza?

▪ Taper angled kana countersink angled

▪ Countersink dhayamita

▪ The rakapedzwa dhayamita pakati nomubato mugomba

▪ Hwakadzama ari countersink rinofanira akachera

Pasi mufananidzo iyo inopa muenzaniso countersink mugomba:

A: Countersink yorusvingo, D: Countersink dhayamita, d: Hole dhayamita, H: Hole udzamu
