Ndiqinisekisa njani ukuthembeka kwe-vias kwibhodi yesekethe eqinile?

Intshayelelo:

Kule post yebhlog, siza kuphonononga ezinye zeetekhnoloji eziphambili kunye nezenzo ezilungileyo onokuzisebenzisa ukuze uqinisekise ukuthembeka kwe-vias kwiibhodi zesekethe eziqinileyo.
Xa uyila iibhodi zeesekethe, ukuthembeka kubalulekile. Inkalo ephambili ekufuneka iqwalaselwe ngokucokisekileyo kukuthembeka kwe-vias kwiibhodi zesekethe eziqinileyo. I-Vias idlala indima ebalulekileyo ekusekeni uqhagamshelwano phakathi kweeleya ezahlukeneyo zesekethe kunye nokuqinisekisa ukuhamba kakuhle kwemiqondiso yombane.

Ngaphambi kokungena kwiinkcukacha, kubalulekile ukuqonda ingcamango esisiseko ye-vias. I-Vias yimingxuma emincinci egrunjiweyo ngokugqunywa kwebhodi yesekethe ukuvumela ukudityaniswa kombane phakathi kweeleya ezahlukeneyo. Kwiibhodi zesekethe eziguquguqukayo ezidibanisa i-flexible substrates kunye ne-rigid substrates, i-vias kufuneka yenzelwe ukujamelana noxinzelelo kunye noxinzelelo oluhambelana nokugoba kunye nokuguquka.

Ukuqinisekisa ukuthembeka kwe-vias kwiibhodi zesekethe eziguquguqukayo, nantsi imiba esisiseko:

1. Lungisa ngokubeka:
Indawo kunye nokuhanjiswa kwe-vias kubalulekile ekugcineni ukuthembeka. Kubalulekile ukubeka i-vias kwiindawo zesekethe kunye nokugoba okuncinci kunye nokuguquguquka. Oku kunceda ukunciphisa uxinzelelo kwi-vias kwaye kuthintele ukuba bangonakali ngexesha lobomi bebhodi.

2. Ngokusetyenziswa kobungakanani kunye nomlinganiselo wembonakalo:
Ubungakanani kunye nomlinganiso we-a via kwakhona kuchaphazela ukuthembeka kwayo. I-diameter encinci ye-vias ayinakuchaphazeleka kancinci kuxinzelelo lomatshini kwaye iyaxhathisa ngakumbi ekungaphumeleli. Ukongeza, umlinganiselo wembonakalo (umyinge wokudlula ubunzulu ukuya kwidayamitha) kufuneka ube ngaphakathi kwemida eyamkelekileyo ukunqanda iingxaki ezinje ngee-plating voids okanye iintanda.

3. Iphedi kunye noyilo lweringi:
Uyilo lwepadi kunye neringi ejikeleze i-via idlala indima ebalulekileyo ekuthembekeni kwayo. Ipeyidi eyaneleyo kunye nemilinganiselo yeringi kufuneka igcinwe ukuze kuqinisekiswe ukudibanisa okuthembekileyo kwe-solder kunye nokudibanisa okufanelekileyo kombane. Iipads ezingaphantsi okanye iiringi zinokubangela uqhagamshelo lomatshini olubuthathaka kunye neengxaki zombane.

4. Ukusetyenziswa kwemingxuma:
Kwiibhodi zesekethe eziguquguqukayo, kuyacetyiswa ukuba usebenzise imingxunya endaweni yokungaboni okanye ukungcwatywa kwe-vias xa kunokwenzeka. Ngemingxuma inika amandla angcono oomatshini kunye noqhagamshelo lombane. Bakwavumela uvavanyo olulula kunye nokuhlolwa ngexesha lenkqubo yokuvelisa.

5. Ukukhethwa kwezinto:
Ukukhetha imathiriyeli echanekileyo yokudlula kubalulekile ekuthembekeni kwayo. Izinto ezikumgangatho ophezulu ezifana ne-electroless copper okanye i-nickel plating (i-nickel engena-electroless, i-electroless palladium, igolide yokuntywila) inokunyusa ukuqina kunye nokuphila ixesha elide lemingxuma, ngakumbi kwiimeko ezinzima zokusingqongileyo.

6. Ulawulo lobushushu:
Ulawulo olufanelekileyo lwe-thermal lunokwandisa ukuthembeka kwe-vias kwiibhodi zesekethe eziqinileyo. Ngobuchule ibekwe vias thermal uncedo ukutshabalalisa ubushushu, ukunciphisa umngcipheko thermal umonakalo ebhodini kunye namacandelo ayo.

7. Thobela imigangatho yoshishino:
Ukulandela imigangatho yoshishino kunye neenkcukacha kubalulekile ekuqinisekiseni ngokuthembeka. Imigangatho efana ne-IPC-2223 inika isikhokelo ngoyilo, imathiriyeli, kunye nokuphunyezwa. Ukuthotyelwa kwale migangatho kuqinisekisa ukuhambelana kwaye kwandisa ukuthembeka ngokubanzi kwebhodi.

8. Uvavanyo olungqongqo kunye nokuhlolwa:
Ukuvavanya ngokucokisekileyo kunye nokuhlolwa kweebhodi zesekethe eziqinileyo, kubandakanywa ne-vias, kubalulekile ukufumanisa nayiphi na imiba enokubakho ngaphambi kokuthunyelwa. Iindlela zokuvavanya ezingonakalisi ezifana nokuhlolwa kwe-X-reyi zinokunceda ukuchonga naziphi na iziphene okanye izitenxo kwi- vias ukuze kuthathwe amanyathelo okulungisa ngokukhawuleza.

Ngokuphumeza ezi zenzo zingcono kunye nokuqwalaselwa, abayili banokuphucula ngokubonakalayo ukuthembeka kwe-vias kwiibhodi zesekethe eziqinileyo. Kubalulekile ukusebenza nomvelisi onamava kwaye udibane neengcaphephe kwinkalo yokuqinisekisa ukuba kuphunyezwe okuthembekileyo nokomeleleyo ngokuyilwa.

Isishwankathelo

Ukuthembeka kwe-vias kwiibhodi zesekethe eziguquguqukayo zibalulekile kwaye zifuna ukuqwalaselwa ngenyameko. Ngokusetyenziswa ngokufanelekileyo ngokucwangcisa, ubungakanani kunye noyilo, ukhetho lwezinto eziphathekayo, ulawulo lwe-thermal, ukuthotyelwa kwemigangatho yoshishino kunye novavanyo olungqongqo, abaqulunqi bebhodi yesekethe banokuqinisekisa impumelelo kunye nokuthembeka kweeprojekthi zabo. Ukutyala ixesha kunye nomzamo wokuphucula uyilo lwemingxuma kuya kukhokelela ekusebenzeni ngcono, iibhodi eziguquguqukayo eziqinileyo.
