1. Yintoni i-telling yangasemva?

Ukubuyela umva kuhlobo olukhethekileyo lwe-hole enzulu yokuqhuba. Kwimveliso yeeBhodi zemisebenzi emininzi, ezinje ngeebhodi ezili-12, kufuneka sidibanise umaleko wokuqala kumbethe wesithoba. Ngokwesiqhelo, sirhuqa umngxunya (i-drill enye) kwaye emva koko i-tenper.in ngale ndlela, umgangatho wokuqala uqhagamshele ngqo kumgangatho we-12. Ngapha koko, sifuna kuphela umgangatho wokuqala ukuba uqhagamshele kumgangatho we-9, kunye nomgangatho we-10 ukuya kumgangatho we-12 kuba intsika yengqibelelo ichaphazela i-SIFALS (i-STARD). Ubhedu oluncinci, kwaye icebiso le-Drill ngokwalo libonisa. Ubude be-stub bale stab bubizwa ngokuba yixabiso le-B, oko ngokubanzi kuluhlu lwe-50-15050.

2. Iluncedo lokuntywila okungasemva

1) nciphisa ukuphazamiseka kwengxolo

2) Ukuphucula ingqibelelo yomqondiso

I-3) Ubuninzi bendawo yengingqi ihla

4) Ukucutha ukusetyenziswa kwemingxunya engaboniyo kwaye kunciphisa ubunzima bemveliso ye-PCB.

I-3. Ukusetyenziswa kwengubo yangasemva

Buyela kwi-Drill I-Drill ayinalo naluphi na unxibelelwano okanye isiphumo secandelo lomngxunya, ukuphazamiseka ", ukusasaza", ukugcwalisa, njl njl.

4. Umgaqo wokuSebenza wokuSebenzisa umva

Xa inaliti yokuqhuba iyothusa, i-Microld yangoku iveliswe xa i-Drill Inaliti inxibelelana ne-foil yobhedu kwiplate yeplate, kwaye ke idrill iyakwenziwa xa ubunzulu obusezantsi kufikelwa xa ubunzulu obukhululekileyo bufikelwa nini.

5. Inkqubo yokuqhuba ivelisi yemveliso

1) Nikezela i-PCB ngomngxunya wesixhobo. Sebenzisa umngxunya wokufumana isixhobo sokubeka i-PCB kwaye udle umngxunya;

I-2) i-elektroplaplating i-PCB emva kokubamba umngxunya, kwaye itywine umngxunya ngefilimu ewomileyo ngaphambi kokufakwa kwe-elektroppoplat;

3) Yenza imizobo yangaphandle kwi-PCB ye-elektroniki;

4) Yenza i-elektroproplay kwi-PCB emva kokwenza iphethini yangaphandle, kwaye wenze ifilimu eyomileyo yokutywina komngxunya wokuma ngaphambi kwemfuza;

5) Sebenzisa umngxunya wokubeka esetyenziswa yi-Drill enye ukuya kwindawo yasemva, kwaye usebenzise i-Drill Cutter ukuba ibuyele umngxunya wokugcina i-elektronisi ekufuneka ibuyile;

I-6) Hlamba i-Drill yokuKhangela emva kwexesha lokubuyela umva ukuze ususe ukusikwa kwentsalela kwidrile yasemva.

I-6. Iimpawu zobugcisa zeplate yokuqhuba ngasemva

I-1) IBhodi yeBhodi (uninzi)

2) Ngokwesiqhelo yi-8 - 50 yee-50

I-3) ubukhulu beBhodi: ngaphezulu kwe-2.5mm

I-4) Ububanzi be-muntick bukhulu

5) Ubungakanani bebhodi bukhulu

I-6) Ubuncinci beHole yeHard ye-Drill yokuqala> = 0.3mm

I-7) Isiphaluka esingaphandle siphantsi, uyilo oluninzi ngakumbi kwimbonakalo yoxinzelelo

I-8) Umngxunya ongasemva uhlala u-0.2mm omkhulu kunomngxunya ofuna ukuba unxitywe

I-9) Ukunyamezelana okunzulu yi + /- 0.0mmm

I-10) Ukuba i-Drill yangasemva ifuna ukubaleka kwi-MARDE

7.Ukusebenza okuphambili kweplate yokuhamba ngasemva

Izixhobo zonxibelelwano, iseva enkulu, i-elektroniki ze-elektroniki, emkhosini, i-aerospace kunye namanye amasimi. Njengomkhosi kunye ne-aerospace ngamashishini anovakalelo, i-backplae yendawo yasekhaya idla ngokubonelelwa liziko lophando, iZiko lokuThumela umkhosi.
