Kwinkqubo yokwenza iPCB, siya kudibana nengxaki yokuqulunqa. Ke ngoko, namhlanje ndifuna ukuthetha nawe malunga neendlela zangoku zokuqamba zePCB, kubandakanya oku kulandelayo:

1, Akukho sithuba semosaic
Isithuba sokubumba simahla kukususa isithuba phakathi kweyunithi encinci iibhodi PCB. Ngale ndlela, akukho sikhewu phakathi kweebhodi ezincinci zePCB ebhodini, ezinokukhokelela ekunyamezelweni kobume bebhodi yePCB. Ke ngoko, le mowudi yokwakheka ingasetyenziselwa iibhodi zePCB ezineemfuno zemilo ye-lax. Kuyilo lwebhodi yePCB eneemfuno ezingqongqo zemilo, kuyacetyiswa ukuba uyiphephe le ndlela yokwakheka kangangoko kunokwenzeka.

2, i-Zigzag mosaic
Ukubunjwa kwefom yokubuyela umva yindlela yokuqulunqa eyamkelwa ngabasebenzi bokulungiselela ubunjineli phambi kwemveliso ukwenzela ukwandisa izinga lokusetyenziswa kwe-chip enye kunye nokunciphisa inkunkuma ye-gap nganye ye-chip enye. Njengoko kuboniswe kuMfanekiso 1, inokuphucula ngokufanelekileyo izinga lokusetyenziswa kwezinto.

3. Ukubuyela umva ukuthunga
I-Reverse stitching yindlela yokusebenzisa ngokupheleleyo indawo yetemplate ngokudibanisa umva wokuthunga. Kukho iimeko ezimbini eziqhelekileyo ze-flip flopping: okokuqala, imilo yeyunithi encinci ye-PCB “yimilo engu-L” kwaye ijikelezwe enye kwenye, kwaye ke imilo yeyunithi encinci ye-PCB “yimilo ka-T” kwaye ijikelezwe enye kwenye. .

4. Ukwakhiwa kwenkqubo
Ukwakhiwa kwenkqubo kukuqulunqa inkqubo enkulu kwicam ukungenisa imilo ephezulu yeyunithi encinci yebhodi yesekethe yePCB, kwaye ucofe ngokuthe ngqo umsebenzi wokuqamba ukugqiba umsebenzi wokuqamba. Qaphela: kwinkqubo yokuvala i-PCB, kufuneka isetyenziswe njengowona mgca mkhulu webhodi yesekethe. Ngaphandle koko, kufuneka isetyenziswe njengenkcazo yebhodi yesekethe. Kwinkqubo yokuvala ibhodi yesiphaluka, kufuneka ilungiswe ngokuzenzekelayo njengenkcazo yebhodi yesekethe. Le ndlela inciphisa iimpazamo ezibangelwa yimiba yabantu kwaye iphucula ukusebenza kakuhle kokwenza. Yenza inkqubo kunye nebhodi “e-T-shaped” kwi-Figure 3, kwaye iziphumo ziboniswe kwi-Figure 4. Ngenxa yokuba azikho iibhodi ezininzi ezikhethekileyo, indibano yesicelo iqhutyelwa kwiimeko ezininzi kwiifektri zebhodi yesekethe yePCB.

5. Ukwakhiwa okuxutyiweyo
Ukuqulunqwa kweHybrid kukukhetha ezona ndlela zingasentla zokuqulunqa kunye nokufunxa izibonelelo zeendlela ezahlukeneyo zokuqulunqa, ezinokuphucula ngokufanelekileyo izinga lokusetyenziswa koyilo kunye netshiphu enye. Thatha i-“T-shaped” yokubunjwa kwe-reverse stitching kuMfanekiso 3 njengomzekelo. Ukuba le ndlela yokwakheka itshintshile kancinane, izinga lokusetyenziswa kwetshiphu enye liya kuphuculwa.

Okokuqala, ibhodi yesekethe ye-PCB encinci idityaniswe ukuze yenze iyunithi enkulu “e-L-shaped”, kwaye ke indibano iqhutywe ngokuhambelana ne-back shape assembly. Ekugqibeleni, iyunithi encinane yongezwa ukuze kugqitywe indibano.

Ngokwahlukileyo Abavelisi bePCB, indlela yokukhetha ukwakheka nayo yahlukile. Kwimeko yebhetshi encinci kunye neentlobo ezininzi, ukubunjwa kweprogram kunokuqwalaselwa, kunye nexesha elifutshane lokuqulunqa kunye nesantya esiphantsi sephutha; Ukuveliswa kobuninzi, kufuneka siqwalasele izinga lokusetyenziswa kwezinto kunye nezixhobo zebhotile, kunye nezinye iindlela zokuqulunqa.
