Menene Ramin Counterbore?
Ramin daɗaɗɗen ramuka shine hutun siliki akan PCB wanda ke da diamita mafi girma a saman saman da ƙaramin diamita a ƙasa. Manufar ramin da aka yi amfani da shi shine don ƙirƙirar sarari don dunƙule kai ko flange na bolt, ƙyale shi ya zauna tare da ko ɗan ƙasa da saman PCB. Mafi girman diamita a saman yana ɗaukar kai ko flange, yayin da ƙaramin diamita yana tabbatar da cewa ramin maɗaurin ko jikin ya dace da kyau.
Menene Countersunk Hole?
A gefe guda kuma, rami mai jujjuyawa shine hutun juzu'i akan PCB wanda ke ba da damar shugaban dunƙule ko kusoshi ya zauna tare da saman PCB. Siffar ramin countersunk ya yi daidai da bayanin martabar kan maɗaurin, yana haifar da ƙasa mara kyau da daidaito lokacin da aka shigar da dunƙule ko kulli. Ramin Countersunk yawanci suna da gefen kusurwa, sau da yawa 82 ko 90 digiri, wanda ke ƙayyade siffar da girman kan maɗauri wanda zai dace da wurin hutu.
Counterbore VS Countersunk: Geometry
Duk da yake duka ramukan counterbore da countersunk suna yin amfani da manufar ɗaukar kayan ɗamara, babban bambancinsu ya ta'allaka ne a cikin lissafi da nau'ikan kayan ɗamara da suke ɗauka.
