Ngobuninzi beemveliso ze-elektroniki kunye nemveliso ye-elektroniki engenazikhokelo, inqanaba lobuchwephesha kunye neemfuno zomgangatho wePCB kunye I-PCBA iimveliso nazo zijamelene nemingeni enzima. Kwinkqubo yoyilo lwe-PCB, imveliso, ukuqhubekeka kunye nendibano, inkqubo engqongqo kunye nolawulo lwempahla eluhlaza ziyafuneka. Ngenxa ubuchule kunye neteknoloji nangoku kweli xesha lotshintsho ngoku, ukuqonda umthengi ukuba PCB kunye nenkqubo ibandla umahluko omkhulu, ngoko efanayo ukuvuza, kunye nesekethe evulekileyo (umgca, umngxuma), welding, ezifana imbabala ipleyiti ukusilela kumaleko kudla ngokwenzeka, okuhlala kubangela uxanduva olusemgangathweni lwempikiswano phakathi kwabanikezeli kunye nabasebenzisi, oku kukhokelele kwilahleko enkulu yezoqoqosho. Ngokusebenzisa uhlalutyo lokungaphumeleli kwe-PCB kunye ne-PCBA yokusilela kwesenzeko, ngothotho lohlalutyo kunye nokuqinisekisa, fumana unobangela wokungaphumeleli, ukuphonononga indlela yokusilela, ukuphucula umgangatho wemveliso, ukuphucula inkqubo yemveliso, ukusilela kwengozi yokulamla kubaluleke kakhulu.

Uhlalutyo lokusilela kwePCB:

1.Nceda abavelisi ukuba baqonde umgangatho wemveliso, bahlalutye kwaye bavavanye ubume benkqubo, balungiselele kwaye baphucule uphando lwemveliso kunye neenkqubo zophuhliso kunye neenkqubo zemveliso;

2. Ukuchonga oyena nobangela wokungaphumeleli kwindibano ye-elektroniki, ukubonelela ngesicwangciso senkqubo yokuphucula inkqubo yendibano, kunye nokunciphisa iindleko zokuvelisa;

3. Ukuphucula izinga elifanelekileyo kunye nokuthembeka kweemveliso, ukunciphisa iindleko zolondolozo, kunye nokunyusa umgangatho wokhuphiswano lophawu lweshishini;

4. Cacisa iqela elinoxanduva elibangela ukusilela kwemveliso ukubonelela ngesiseko sokugweba.

Yintoni uhlalutyo lokusilela kwe-PCB

Uhlalutyo lokusilela kwe-PCB kweenkqubo ezisisiseko

Ukufumana esona sizathu okanye indlela yokusilela kwe-PCB okanye isiphako, imigaqo-siseko esisiseko kunye neenkqubo zohlalutyo kufuneka zilandelwe, kungenjalo ulwazi lokungaphumeleli olusebenzayo lunokuphoswa, okukhokelela ekusileleni kohlalutyo okanye kwisigqibo esingalunganga. Inkqubo ngokubanzi esisiseko kukuba, ngokusekwe kwimeko yokusilela, indawo yokungaphumeleli kunye nemowudi yokusilela kufuneka ichongwe ngokuqokelelwa kolwazi, ukuvavanywa kokusebenza, ukuvavanywa kokusebenza kombane kunye nokuhlolwa kokubonakala okulula, oko kukuthi, indawo yokusilela okanye indawo enesiphoso.

Kwi-PCB elula okanye i-PCBA, indawo yokusilela kulula ukuyichaza, kodwa kwi-BGA okanye i-MCM ehambelana nezixhobo okanye ii-substrates, isiphene akukho lula ukujonga ngemicroscope, akukho lula ukuyichaza ngelo xesha, ngeli xesha kufuneka Sebenzisa ezinye iindlela ukumisela.

Ke kuyafuneka ukuhlalutya ukungaphumeleli, oko kukuthi, sebenzisa iindlela ezahlukeneyo zomzimba kunye neekhemikhali ukuhlalutya indlela ekhokelela ekusileleni kwe-PCB okanye isiphene, ezinje nge-welding ebonakalayo, ungcoliseko, umonakalo owenzekileyo, uxinzelelo olumanzi, umhlwa ophakathi, ukonakala kokudinwa, i-CAF okanye ukufuduka kwe-ion, uxinzelelo olukhulu, njl.

Enye into kukusilela kohlalutyo, oko kukuthi, kusekwe kwindlela yokusilela kunye nohlalutyo lwenkqubo, ukufumana unobangela wokungaphumeleli, ukuba kunyanzelekile, ukuvavanywa kovavanyo, ngokubanzi njengokuqinisekisa kovavanyo, ngokuqinisekiswa kovavanyo kunokufumana esona sizathu sokungaphumeleli .

Oku kubonelela ngesiseko ekujoliswe kuso sokuphucula okulandelayo. Okokugqibela, ingxelo yohlalutyo yokusilela ilungiselelwe ngokweedatha zovavanyo, iinyani kunye nezigqibo ezifunyenwe kwinkqubo yohlalutyo. Iinyani zengxelo kufuneka zicace, ingqiqo iya kuba ngqongqo, kwaye ingxelo ihlelwe kakuhle.

Kwinkqubo yohlalutyo, ingqalelo kufuneka ihlawulwe ekusetyenzisweni kweendlela zohlalutyo ukusuka ezilula ukuya kwezintsonkothileyo, ukusuka ngaphandle ukuya ngaphakathi, ungaze utshabalalise isampulu kwaye emva koko kumgaqo osisiseko wokusebenzisa intshabalalo. Ngale ndlela kuphela apho sinokuthintela ukulahleka kolwazi olubalulekileyo kunye nokwaziswa kweendlela ezintsha zokungaphumeleli.

Njengengozi yemoto, ukuba elinye icala lengozi litshabalalisile okanye lasaba kwindawo leyo, kunzima emapoliseni aseGaomin ukuba achaze uxanduva ngokuchanekileyo, ke imithetho yezendlela kunye nemigaqo ngokubanzi ifuna umntu obaleke kwindawo leyo okanye otshabalalise Indawo yokuthatha uxanduva olupheleleyo.

Uhlalutyo ukusilela PCB okanye PCBA efanayo. Ukuba amalunga e-solder angaphumelelanga ayalungiswa nge-iron soldering iron okanye i-PCB isikwe kakhulu ngesikere esikhulu, emva koko uhlalutyo ngokutsha akunakwenzeka ukuba luqale. Indawo yokungaphumeleli itshatyalalisiwe. Ngokukodwa kwimeko yenani elincinci leesampulu ezingaphumelelanga, nje ukuba imeko yendawo engaphumeleliyo itshatyalaliswe okanye yonakaliswe, oyena nobangela wokungaphumeleli awunakufumaneka.
