PCB ukwenziwa kwembonakalo yokwazisa

Ukufakwa kwe-PCB, umngxunya kunye nokuma kwemilo kunokusebenzisa indlela yokufaka into yokufa, ekuqhubeni i-PCB elula okanye i-PCB ngaphandle kweemfuno eziphezulu kakhulu kunokusebenzisa indlela yokufaka. Ukulungele ukuveliswa kwenqanaba eliphantsi kunye nePCB enkulu kunye neemfuno ezingekho phezulu kakhulu kwaye kungabi yimfuno ephezulu kakhulu, enexabiso eliphantsi.

Inqindi:

Ukuveliswa kwebhetshi enkulu, uhlobo kunye nenani lemingxunya kunye nemilo entsonkothileyo yamacandelo emacaleni enye kunye necala eliphindwe kabini elingenasinyithi le-epoxy yeglasi yengubo, ihlala isebenzisa ukubetha okanye ukubetha okuninzi.

Ukulungiswa kwemilo:

Imveliso yebhodi eprintiweyo yevolumu enkulu yepaneli enye kunye nemilo ephindwe kabini, ihlala ifile. Ngokobungakanani bebhodi eprintiweyo, inokwahlulwahlulwa kwaba kufa okuphezulu kunye nokuwa.

Inkqubo edibeneyo:

Ukwenzela ukunciphisa umjikelo wokuvelisa kunye nokuphucula imveliso, idityaniswa die isetyenziselwa ukwenza imingxunya kunye neemilo zepaneli enye ngaxeshanye.

Ukucwangcisa ibhodi eprintiweyo ngesikhunta, eyona nto iphambili kuyilo kunye nokuqhubekeka kwesikhunta, esidinga ulwazi lobuchwephesha. Ukongeza, ukufakwa kunye nokulungiswa kwesikhunta kubalulekile kakhulu. Okwangoku, uninzi ukungunda abavelisi PCB kusingathwa mveliso zangaphandle.

Amanyathelo okhuseleko lofakelo sokubumba:

1. Ngokokubala koyilo lokufa kwamandla angenanto, ubungakanani besafa, ukuphakama kokuvalwa kokukhethwa komatshini wokushicilela (kubandakanya uhlobo, itoni).

2. Qalisa inqindi, jonga iklatshi, i-brake, isilayida kunye nezinye izinto ziqhelekile, indlela yokusebenza ithembekile, akufuneki kubekho mpembelelo iqhubekayo.

3. I-pad yentsimbi phantsi kwesifa, ngokubanzi iziqwenga ezi-2, kufuneka inyathelwe kwi-grinder ngaxeshanye, ukuqinisekisa ukuba idiski ifakwe ngokungqinelanayo kwaye ime nkqo. Ukubekwa kwepad yentsimbi kwindawo yokutsiba engakuthinteli ukuwa kwezinto ngaxeshanye kufutshane neziko lokungunda.

4. Lungisa iiseti ezininzi zokucinezela ipleyiti kunye ne-T-head yokucinezela i-screws yeplate yokusetyenziswa ngokuhambelana nokubumba. Isiphelo sangaphambili seplate cofa akufuneki sichukumise udonga oluthe nkqo lwediski esezantsi. Ilaphu le-Emery kufuneka libekwe phakathi kweendawo zonxibelelwano kwaye izikrufu kufuneka ziqinisiwe.

5. Xa ufaka ukungunda, nikela ingqalelo kwizikrufu kunye namandongomane kwizantsi esezantsi ukuze ungachukumisi idiski ephezulu (amathontsi aphezulu afe aze avale).

6. Xa uhlengahlengisa ukungunda, zama ukusebenzisa iincwadana endaweni yemoto.

7. Ukulungiselela ukuphucula ukusebenza okungenanto kwe-substrate, iphepha elingaphantsi kufuneka lifudunyezwe. Iqondo lobushushu ukuya kuma-70 ~ 90 ℃ lelona lifanelekileyo.

Umngxuma kunye nokumila kwebhodi yokushicilela yokufa engenanto inezi ziphene zomgangatho zilandelayo:

Ukuphakanyiswa ujikeleze umngxunya okanye ifoyile yobhedu ejijekileyo okanye eyahlukileyo; Kukho iintanda phakathi kwemingxunya; Ukuphambuka kwendawo yeHole okanye umngxunya ngokwawo awume nkqo; Burr; Icandelo elibi; Ibhodi eprintiweyo isontekile ezantsi embizeni; Izinto ezilahliweyo ezitsiba phezulu; Ijam yenkunkuma.

Amanyathelo okuhlola kunye nohlalutyo ngala alandelayo:

Jonga ukuba ngaba ukubetha ngenqindi kunye nokuba ngqongqo kwe-punch press kwanele; Uyilo lokufa lunengqiqo, luqinile ngokwaneleyo; I-convex, i-concave die kunye nekholamu yesikhokelo, isikhokelo sokuchaneka kwemikhono yesikhombisi kufezekisiwe, ukufakela kugxile, nkqo. Nokuba ukulingana kufanelekile kunjalo. Umsantsa phakathi kwe-convex kunye ne-concave incinci kakhulu okanye inkulu kakhulu ukuvelisa iziphene ezisemgangathweni, eyona ngxaki ibaluleke kakhulu kuyilo lokungunda, ukulungisa, ukulungisa ingxaki kunye nokusetyenziswa. I-convex kunye ne-concave die edges azivumelekanga ukuba zijikelezwe zize zitshintshwe. I-Punch ayivumelekanga ukuba ne-taper, ngakumbi xa ukubetha kokubini okuqhelekileyo kunye nokujika okungavumelekanga. Kwimveliso, kufuneka sihlale sinikele ingqalelo ekubeni umda we-convex kunye ne-concave die unxityiwe. Ukukhupha umlomo kunengqiqo, ukuxhathisa okuncinci. Cofa ibhodi yezinto eziphathekayo, intonga ebonakalayo inengqiqo, amandla aneleyo. Ubunzima beplate kunye namandla okubopha we-substrate, isixa seglue, kunye namandla okubopha ifoyile yobhedu, ubushushu kunye nokufuma kunye nexesha zizinto ezinokuthi ziqwalaselwe kuhlalutyo lokungabinanto kweziphene zomgangatho.
