Iibhodi zeesekethe ezininzi |INdibano kunye nomgangatho welding |iintanda ze-welding |ukuchithwa kweepadi

Indlela yokuqinisekisa ukudibanisa kunye nomgangatho we-welding yeebhodi ze-multi-circuit kwaye ugweme iintanda ze-welding kunye neengxaki zokuchithwa kweepadi?

Njengoko imfuno yezixhobo ze-elektroniki iqhubeka ikhula, imfuno yeebhodi ezithembekileyo kunye nekhwalithi ephezulu yeesekethe ezininzi ziye zabaluleka.Ezi bhodi zeesekethe zidlala indima ebalulekileyo ekuqinisekiseni ukusebenza ngokufanelekileyo kwezixhobo zombane.Nangona kunjalo, ngexesha lendibano kunye nenkqubo ye-welding yeebhodi zeesekethe ze-multi-layer, ukuba aziphathwanga ngokufanelekileyo, iingxaki ezinjenge-welding cracks kunye ne-pad peeling zingenzeka.Kule posi yebhlog, siza kuxoxa ngeendlela ezisebenzayo zokuqinisekisa umgangatho we-multi-circuit board assembly kunye ne-soldering kunye nokuthintela ezi ngxaki ukuba zingenzeki.

I-Capel yinkampani eneminyaka eyi-15 yamava eprojekthi kunye nobuchwepheshe boshishino lobuchwephesha.Ngeqela elomeleleyo kunye noomatshini abagqibeleleyo abazenzekelayo ngokupheleleyo, baye baba ngumvelisi othembekileyo kumashishini.Ubuchule babo bokuvelisa obungqongqo kunye nobuphezulu obudityaniswe nezakhono zenkqubo ephucukileyo bubenza bakwazi ukuvelisa iibhodi zeesekethe ezikumgangatho ophezulu, ezinemisebenzi emininzi.

Ukuqinisekisa umgangatho wokuhlanganisa kunye nokuwelda kweebhodi zeesekethe ezininzi, kufuneka kulandelwe la manyathelo abalulekileyo alandelayo:

1. Khetha imathiriyeli efanelekileyo:Ukukhethwa kwezinto eziphathekayo kubalulekile ekumiseleni umgangatho jikelele webhodi yesekethe.Khetha izixhobo ezikumgangatho ophezulu ezihlangabezana nemigangatho efunekayo.Oku kuya kunceda ukuthintela iingxaki ezinxulumene nokuqhekeka kwe-solder kunye ne-pad detachment.

2. Ulawulo lomgangatho kwinqanaba ngalinye:Ukuphumeza inkqubo yolawulo lomgangatho olomeleleyo egubungela inqanaba ngalinye lenkqubo yokwenziwa kwemveliso.Oku kubandakanya ukuhlola izinto ezingenayo, ukubeka esweni inkqubo yokuvelisa kunye nokuvavanya ngokucokisekileyo imveliso yokugqibela.Ukuhlolwa rhoqo kunokunceda ukubona naziphi na iziphene okanye iingxaki kwangethuba, ukunciphisa amathuba okuqhekeka kwe-solder kunye neengxaki ze-debonded pad.

3. Ukugcinwa nokuphathwa ngendlela eyiyo:Ukugcinwa ngokufanelekileyo kunye nokuphathwa kweebhodi zeesekethe kubalulekile ukugcina ingqibelelo yazo.Qinisekisa ukuba iibhodi zeesekethe zigcinwa kwindawo elawulwayo kunye nomswakama owaneleyo kunye nobushushu.Ziphathe ngononophelo ukuthintela nawuphi na umonakalo onokuthi ubangele iintanda okanye iipads ziwe.

4. Uyilo oluchanekileyo kunye noyilo:Landela uyilo olusemgangathweni lweshishini kunye nezikhokelo zoyilo ukuqinisekisa ukusebenza okufanelekileyo kunye nokuthembeka kwebhodi.Uyilo olulungiselelwe kakuhle lunokunciphisa uxinzelelo kumacandelo ngexesha lokudibanisa kunye ne-welding, ngaloo ndlela ukunciphisa ithuba lokuqhekeka okanye ukuchithwa.

5. Eyona ndlela ilungileyo yokuhlanganisa:Sebenzisa iindlela ezifanelekileyo zokuhlanganisa ezihambelana neemfuno ezithile zebhodi.Qwalasela izinto ezifana nobukhulu becandelo, indlela ye-soldering kunye neprofayili ye-reflow ukuqinisekisa ukuba i-solder eqinile kwaye inokuthenjwa.Ukulawula ukushisa okufanelekileyo ngexesha le-welding kubalulekile ekunqandeni ukukrazula kunye nokukhupha.

6. Uvavanyo olubanzi:Uvavanyo olubanzi lwebhodi yesekethe edibeneyo ukuqinisekisa ukusebenza kwayo kunye nomgangatho.Oku kubandakanya uvavanyo lombane, uvavanyo olusebenzayo kunye nokuvavanya ukuthembeka.Uvavanyo lunceda ukuchonga nayiphi na imiba enokuthi yenzeke ngexesha lokudityaniswa kunye ne-soldering ukuze kuthathwe amanyathelo okulungisa ngaphambi kokuba ibhodi ifike kumsebenzisi wokugqibela.

Ngokuthobela ezi zikhokelo, abavelisi banokuphucula kakhulu umgangatho we-multi-board assembly kunye ne-soldering.Indlela engqongqo yeCapel kumava ebhodi yesekethe iqinisekisa ukuba iinkqubo zabo zokuvelisa ziphuculwe ukuvelisa iibhodi zesekethe ezikumgangatho ophezulu kunye nokunciphisa amathuba okuqhekeka kwe-solder kunye nemiba yokukhupha i-pad.

Isishwankathelo,ukuqinisekisa umgangatho wokuhlanganisa kunye nokuthengiswa kweebhodi zeesekethe ezininzi kubaluleke kakhulu ekusebenzeni ngokubanzi kunye nokuthembeka kwezixhobo zombane.Ngokulandela la manyathelo angentla kwaye ukhethe umenzi othembekileyo onamava afana nabavelisi baseCapel banokunciphisa umngcipheko wokuqhekeka kwe-solder kunye ne-pad detachment.Utyalo-mali kwizinto ezikumgangatho ophezulu, ukuphumeza iinkqubo zokulawula umgangatho owomeleleyo, kunye nokusetyenziswa kobuchule bokuhlanganisana obufanelekileyo kubalulekile ekuveliseni iibhodi zeesekethe ezininzi ezithembekileyo nezizinzileyo.
