Ezinye iingxaki kunye nendlela yokulawula i PCB Indlela yeplagi yinto abantu abaninzi abafuna ukuyazi, ke eli nqaku likuzisela olu lwazi.

Okokuqala, unobangela wengxaki

Ngophuculo oluqhubekayo lokuchaneka kokwenziwa kwe-PCB abavelisi, abavelisi beebhodi zeesekethe ezidlula umngxuma ezenziwe ziisekethe eziprintiweyo ze-PCB baya besiba ncinci kwaye bencinci. Ngokumalunga neebhodi zemveliso ezombiweyo ngoomatshini, kwimingxuma enobubanzi obuyi-0.3mm iyinto eqhelekileyo, kwaye i-0.25mm okanye i-0.15mm nayo ayinasiphelo. Njengoko i-aperture iyancipha, yiplagi ephumela kumngxuma. Emva kokufaka umngxuma, ipleyiti idla ngokuphuka ngaphandle kokwaphuka. Umlinganiselo wombane awukwazi ukulinganisa isiseko, kwaye ekugqibeleni ugeleza kumxhasi. Emva kwe-welding yobushushu obuphezulu, ukothuka kwe-thermal kunye nendibano, isicelo sikwi-East Window kuphela. Liphelile ixesha lokucinga ngayo ngoku!

Ukuba unokuqala kwinkqubo yokuvelisa, unokusebenzisa iiplagi zemingxuma nganye nganye ukukhusela ukuvala kakubi. Oku kuya kuba yindlela efanelekileyo yokuphucula umgangatho. Mna ngokwam ndizamile ukuxoxa ngomatshini wezinye iiplagi kwinkqubo, kwaye ndibonelele ngeendlela eziluncedo zokusebenza ukuthintela okanye ukunciphisa ukwenzeka kokuvala kakubi.

Okwesibini, hlalutya iiplagi zemingxuma ezimbi kwinkqubo nganye

Sonke siyazi ukuba abavelisi be-PCB banokugrumba, ukwenza i-degumming, i-copper plating, i-plating, i-graphics processing, i-graphics plating kunye nezinye iinkqubo eziphambili kwi-PCB eprintiweyo yokwenza ibhodi yesekethe kunye nokusetyenzwa komngxuma. Ke ngoko, isisombululo seplagi yomngxuma nayo ndiya kwenza enye enye. Yazisa inkqubo nganye.

ukubhola

Iiplagi zemingxuma ezibangelwa ukubhoboza ikakhulu zineentlobo ezilandelayo, kwaye izilayi zento ziboniswa kumzobo ongezantsi.

Qinisekisa

Masishwankathele: Nangona kunjalo, umntu wam akasiyo i-flat drilling. Nangona kunjalo, enyanisweni, ukugrumba kusesinye seziganeko eziphambili zokuplaga kakubi. Ngokohlalutyo lwamanani ombhali, kufumaniseke ukuba i-35% yemingxuma ayinayo i-copper, kwaye i-pluging yemingxuma ebangelwa ku-drilling ihlwempu kakhulu. Ke ngoko, ulawulo lokugrumba lugqaliselo lolawulo olubi lweplagi. Ndicinga ukuba le miba ilandelayo zezona ndawo zolawulo:

1. Ngokweziphumo zovavanyo, kunokuba iinkosi zemveli zithembele kumava okufunda ukuchonga iiparamitha zokomba ezifanelekileyo (imela engezantsi ikhawuleza kakhulu kwaye iplagi ilula);

2. Ulungelelwaniso lwexesha le-drilling rig;

3. Ukuqinisekisa ukuqokelelwa kothuli;

4. Kubalulekile ukwazi ukuba i-drill drill imingxuma kwi-tape ukuzisa iglue emngxunyeni, kunokuba ifake i-tape ngokwayo emngxunyeni. Ngoko ke, i-drill akufanele iqhutywe kwi-tape nanini na;

5. Phuhlisa iindlela eziluncedo zokubona amasuntswana e-drill drill;

6. Abaninzi abavelisi baye baqhuba iipores zokuqokelela uthuli lomoya ophezulu kunye nokususwa kothuli emva kokubhoboza, okunokuphunyezwa;

7. Inkqubo yokuchithwa ngaphambi kokucwiliswa kobhedu kufuneka ibe yi-ultrasonic yokuhlamba kunye nokuhlamba okuphezulu (uxinzelelo olungaphezulu kwe-50KG / CM2).
