Kutheni ukhetha igranite njengenxalenye ye-PCB yokomba kunye nomatshini wokusila?

Njengoko iPCB (iBhodi yeSekethe eShicileleyo) oomatshini bokomba kunye nokusila baye banda kakhulu kwishishini lanamhlanje le-elektroniki, ukukhethwa kwezinto ezifanelekileyo kumacandelo abo kuye kwaba yinto ebalulekileyo ekuqinisekiseni uzinzo kunye nokuqina.Phakathi kwezixhobo ezahlukeneyo ezinokusetyenziselwa ukomba wePCB kunye namacandelo omatshini wokusila, igranite ibonakalise ukuba yenye yezona zinto zithembekileyo kwaye zingabizi kakhulu.

Igranite luhlobo lwelitye lendalo elisetyenziswa kakhulu kulwakhiwo kunye neeprojekthi zobunjineli ngenxa yeempawu zayo ezibalaseleyo, ukuqina, kunye nesibheno sobuhle.Kumxholo wokomba wePCB kunye noomatshini bokungqusha, igranite ixatyiswa ngenxa yokuqina kwayo okuphezulu, i-coefficient yokwandisa i-thermal ephantsi, kunye nobuchule obugqwesileyo bokudambisa ukungcangcazela.Ezi mpawu zenza igranite ibe lolona khetho lufanelekileyo kumatshini wokusebenza, isiseko, kunye neentsika.

Nazi ezinye zezizathu zokuba kutheni igranite ibe lolona khetho lukhethwayo lokwembiwa kwePCB kunye namalungu omatshini wokungqusha:

1. Ukuchaneka okuphezulu kunye nokuzinza

I-Granite inezinga eliphezulu lokuzinza kwe-dimensional ngenxa ye-coefficient yayo yokwandisa i-thermal ephantsi.Le propati ivumela ukubeka okuchanekileyo kunye nokulungelelaniswa kweebhithi ze-drill kunye nezixhobo zokugaya.Ngaphezu koko, i-granite inezinga eliphezulu lokuqina elinceda ukunciphisa ukukhubazeka okubangelwa yinkqubo yomatshini, okubangela ukuchaneka okukhulu kunye nokuhambelana.

2. Ukudambisa ukungcangcazela okugqwesileyo

I-Granite ineempawu ezibalaseleyo zokudambisa ukungcangcazela, ezenza ukuba zilungele izicelo apho uzinzo lubalulekile.Kwi-PCB yokugrumba kunye noomatshini bokugaya, ukukwazi ukudambisa igranite kunceda ukunciphisa ukungcangcazela okubangelwa kukujikeleza ngesantya esiphezulu se-spindle kunye nemikhosi yokusika eyenziwe yinkqubo yomatshini.Oku kukhokelela ekugqityweni komgangatho ophuculweyo, ukunciphisa ukunxiba kwesixhobo, kunye nobomi obude bomatshini.

3. Ixabiso eliphantsi kwaye kulula ukuyigcina

Xa kuthelekiswa nezinye izinto ezifana nentsimbi kunye nentsimbi, igranite ayibizi kakhulu kwaye ifuna ukulungiswa okuncinci.Ukuchasana kwayo ne-abrasion kunye nokulimala kweekhemikhali kuthetha ukuba inokumelana neemeko ezinzima zommandla womatshini ngaphandle kokuthotywa okanye ukubola ngokuhamba kwexesha.Ukongezelela, indawo ye-granite engekho-porous yenza kube lula ukuyicoca kunye nokucoceka, okunceda ukuqinisekisa ukuchaneka kwenkqubo yomatshini.

Ukuqukumbela, ukukhetha i-granite njengenxalenye ye-PCB yokomba kunye noomatshini bokugaya sisigqibo esilumkileyo kubavelisi abafuna ukuqinisekisa ukuchaneka okuphezulu, ukuzinza, kunye nokuqina.Iimpawu zayo zendalo zoomatshini ziyenza ibe yeyona nto ifanelekileyo kumatshini wokusetyenzwa, isiseko, kunye neentsika.Ngaphaya koko, ukusebenza kakuhle kweendleko kunye neemfuno zokugcinwa okuphantsi zenza kube lukhetho olungabizi kakhulu ekulula ukulugcina kumjikelo wobomi bomatshini.
