Izimbobo zokubalazibhobolwa ebhodini lesifunda ngenaliti yokubhoboza ikhanda eliyisicaba noma ummese we-gong, kodwa azikwazi ukubhobozwa (okungukuthi, phakathi kwezimbobo).Ingxenye yoguquko phakathi kodonga lwembobo ku-diameter yembobo engaphandle/enkulu kunawo wonke kanye nodonga lwembobo kububanzi bembobo encane kakhulu ihambisana nendawo ye-pcb.Ingxenye exhuma izimbobo ezinkulu nezincane iyindiza, hhayi indiza ethambekele.
I-Counterbore isetshenziswa kakhulu kumabhodi esekethe ensimbi, njenge-aluminium substrate ne-copper substrate.I-substrate yensimbi inamandla amakhulu emishini futhi akulula ukulimaza isakhiwo se-PCB.
Imbobo, njengoba negama lisho, iphinde ibe imbobo, engadlula ezintweni noma uketshezi olunosayizi ofanele,
Umsebenzi uthi:
a.Isetshenziselwa ukuxhumana futhi ingenziwa ibe yi-threaded through-hole.
b.Yenza amasilinda ezinjini zepiston.
c.Empilweni, izingubo namabhulukwe esiwagqokayo nawo ayizibonelo zokusebenzisa imbobo
Imbobo evamile yokugoba iyimbobo yepulaki ene-copper plated.
Ngenxa yomklamo okhethekile we-element foot, ingaxhunyaniswa ngokuqinile nembobo ngokungezwani kwayo kwesakhiwo ngemva kokufakwa emgodini.
Inzuzo ukunciphisa isethi ye-wave soldering yokushisela izingxenye ezinjalo;Uma izimbobo ezinjalo zingafakwanga ekugcineni, kuzoba lula ukushintsha izingxenye.Yiqiniso, ukushintshwa okuphindaphindiwe kuzothinta ukuthembeka komgodi.
Amaphini we-elementi adinga izimbobo zokubopha ngokuvamile ahlinzekwa ngomsebenzi wokunweba, kunomsebenzi wochungechunge.
Ezinye izingxenye zizoshiselwa futhi ngokuhamba kwesikhathi lapho ezinye izingxenye zishiselwe, kanti ezinye ngeke zishiselwe.
I-Counterbore ihlukaniswe ngamagama amathathu:
1. Gcoba ngokugcwele ikhanda lesibophelelo embotsheni yesinyathelo sengxenye, ebizwa ngokuthi i-counterbore
2. Ikhanda le-fastener alishoniswanga ngokuphelele emgodini wesinyathelo wengxenye, ebizwa ngokuthi i-countersink.
3. Ikhanda lesibophelelo ngeke licwile engxenyeni ngokuyisisekelo, futhi imbobo kuphela enendawo eyisicaba yengxenye ebizwa ngokuthi i-fishhole.
Umehluko phakathi kwembobo ye-countersunk kanye ne-countersunk hole ukuthi ingxenye engaphezulu yembobo ye-bolt ivuselelwa kabusha: imbobo ye-countersunk iyisakhiwo se-cylinder esiqondile;Imbobo ye-countersunk iyisakhiwo esingu-45 degree, esibushelelezi kunembobo ephikisayo.
Ukuvuselelwa okungaphezulu kwembobo ye-bolt kungakwazi ukuhlalisa ikhanda le-bolt, ukuze ikhanda le-bolt lingabi ngaphezu kwendawo ezungezile.
