Yenziwa njani iRogers Pcb?

Rogers PCB, eyaziwa ngokuba Rogers Printed Circuit Board, ithandwa kakhulu kwaye isetyenziswa kumashishini ahlukeneyo ngenxa yokusebenza kwayo okuphezulu kunye nokuthembeka. Ezi PCB zenziwa kwizinto ezikhethekileyo ezibizwa ngokuba yiRogers laminate, eneempawu ezizodwa zombane kunye nezomatshini. Kule post yebhlog, siza kuntywila kubuchule bokwenza iRogers PCB, siphonononga iinkqubo, imathiriyeli, kunye noqwalaselo olubandakanyekayo.

Ukuqonda inkqubo yokuvelisa i-Rogers PCB, kufuneka siqale siqonde ukuba zeziphi ezi bhodi kwaye siqonde ukuba i-Rogers laminates ithetha ntoni.IiPCB zizinto ezibalulekileyo zezixhobo zombane, ezibonelela ngezakhiwo zenkxaso ngoomatshini kunye noqhagamshelo lombane. IiPCB zeRogers zifunwa kakhulu kwizicelo ezifuna ukuhanjiswa komqondiso ohamba rhoqo, ilahleko ephantsi kunye nokuzinza. Zisetyenziswa kakhulu kumashishini afana nonxibelelwano, i-aerospace, ezonyango kunye neemoto.

I-Rogers Corporation, umboneleli wezisombululo zemathiriyeli owaziwayo, uphuhlise i-Rogers laminates ngokukodwa ukuze isetyenziswe ekwenzeni iibhodi zesekethe ezisebenza kakhulu. I-Rogers laminate yimathiriyeli edibeneyo ebandakanya ilaphu le-fiberglass elilukiweyo elizaliswe yi-ceramic kunye nenkqubo ye-hydrocarbon thermoset resin. Lo mxube ubonisa iipropathi ezigqwesileyo zombane ezifana nelahleko ephantsi ye-dielectric, ukuhanjiswa kwe-thermal ephezulu kunye nokuzinza okubalaseleyo komgangatho.

Ngoku, makhe sihlolisise inkqubo yokwenziwa kweRogers PCB:

1. Uyilo loyilo:

Inyathelo lokuqala ekwenzeni nayiphi na PCB, kuquka Rogers PCBs, ibandakanya ukuyila ubeko lwesekethe. Iinjineli zisebenzisa isoftware ekhethekileyo ukwenza i-schematics yeebhodi zeesekethe, ukubeka kunye nokudibanisa amacandelo ngokufanelekileyo. Esi sigaba sokuqala soyilo sibaluleke kakhulu ekumiseleni ukusebenza, ukusebenza, kunye nokuthembeka kwemveliso yokugqibela.

2. Ukukhethwa kwezinto:

Nje ukuba uyilo lugqityiwe, ukhetho lwemathiriyeli luba yimfuneko. I-Rogers PCB idinga ukukhetha izinto ezifanelekileyo ze-laminate, kuthathelwa ingqalelo izinto ezifana ne-dielectric efunekayo rhoqo, i-dissipation factor, i-thermal conductivity, kunye neempawu zoomatshini. Rogers laminates ziyafumaneka kwiindidi ezahlukeneyo zamabakala ukuhlangabezana neemfuno isicelo ezahlukeneyo.

3. Sika i-laminate:

Ngoyilo kunye nokukhethwa kwezinto eziphathekayo kugqityiwe, inyathelo elilandelayo kukusika i-laminate yeRogers ngobukhulu. Oku kunokufezekiswa ngokusebenzisa izixhobo zokusika ezikhethekileyo ezifana noomatshini be-CNC, ukuqinisekisa imilinganiselo echanekileyo kunye nokuphepha nayiphi na umonakalo kwizinto eziphathekayo.

4. Ukugrunjwa kunye nokugalelwa kobhedu:

Kule nqanaba, imingxuma ifakwe kwi-laminate ngokoyilo lwesekethe. Le mingxuma, ebizwa ngokuba yi-vias, ibonelela ngoqhagamshelwano lombane phakathi kweeleya ezahlukeneyo zePCB. Imingxuma egrunjiweyo ke icopper plated ukuseka i-conductivity kunye nokuphucula imfezeko yesakhiwo se-vias.

5. Umfanekiso wesekethe:

Emva kokugaya, umaleko wobhedu usetyenziswa kwi-laminate ukwenza iindlela zokuqhuba ezifunekayo ekusebenzeni kwePCB. Ibhodi efakwe ubhedu ifakwe kwizinto ezilula ukukhanya ezibizwa ngokuba yi-photoresist. Uyilo lwesekethe lugqithiselwa kwi-photoresist kusetyenziswa ubuchule obukhethekileyo obufana ne-photolithography okanye i-imaging ngqo.

6. Ukurhweba:

Emva kokuba uyilo lwesekethe luprintwe kwi-photoresist, i-chemical etchant isetyenziselwa ukususa ubhedu olungaphezulu. I-etchant inyibilikisa ubhedu olungafunwayo, ishiya ngasemva iphethini yesekethe efunwayo. Le nkqubo ibalulekile ekudaleni iitrayiti zokuqhuba ezifunekayo kuqhagamshelo lombane lwePCB.

7. Ulungelelwaniso lomaleko kunye nelamination:

Kwii-PCB zeRogers ezinamanqwanqwa amaninzi, iileya ezizimeleyo zilungelelaniswe ngokuchanekileyo kusetyenziswa izixhobo ezikhethekileyo. Ezi maleko zibekwe kunye ne-laminated kunye ukwenza isakhiwo esidibeneyo. Ukushisa kunye noxinzelelo zisetyenziselwa ukubopha ngokwasemzimbeni kunye nombane kwiileyile, ukuqinisekisa ukuqhuba phakathi kwabo.

8. Electroplating kunye nonyango lwangaphezulu:

Ukukhusela i-circuitry kunye nokuqinisekisa ukuthembeka kwexesha elide, i-PCB ingena kwi-plating kunye nenkqubo yonyango yomhlaba. Umaleko obhityileyo wesinyithi (odla ngokuba yigolide okanye inkonkxa) uqatywe phezu kobhedu oluvelileyo. Olu tyaba luthintela ukubola kwaye lubonelela ngomgangatho ofanelekileyo kumacandelo e-soldering.

9. Imaski yeSolder kunye nesicelo sesikrini sesilika:

Umphezulu we-PCB uqatywe ngemaski ye-solder (ngokuqhelekileyo eluhlaza), ushiya kuphela iindawo ezifunekayo zokudibanisa icandelo. Lo maleko okhuselayo ukhusela umkhondo wobhedu kwizinto zokusingqongileyo ezifana nokufuma, uthuli, kunye noqhagamshelwano ngengozi. Ukongeza, iileya zesilika zesikrini zingongezwa ukuphawula uyilo lwecandelo, abaqulunqi bereferensi kunye nolunye ulwazi olufanelekileyo kumphezulu wePCB.

10. Uvavanyo kunye noLawulo loMgangatho:

Nje ukuba inkqubo yokuvelisa igqitywe, uvavanyo olucokisekileyo kunye nenkqubo yokuhlola iyenziwa ukuqinisekisa ukuba iPCB iyasebenza kwaye ihlangabezana neenkcukacha zoyilo. Iimvavanyo ezahlukeneyo ezinjengovavanyo oluqhubekayo, uvavanyo lombane ophezulu kunye novavanyo lwe-impedance luqinisekisa ukuthembeka kunye nokusebenza kwee-PCB zeRogers.

Isishwankathelo

Ukwenziwa kweePCB zikaRogers kubandakanya inkqubo ecokisekileyo ebandakanya uyilo kunye noyilo, ukukhethwa kwezinto, ukusika i-laminates, ukugrumba kunye nokugalelwa kobhedu, umfanekiso wesekethe, ukubetha, ulungelelwaniso lomaleko kunye ne-lamination, iplating, ukulungiswa komphezulu, imaski ye-solder kunye nezicelo zokuprinta isikrini kunye nokucokisekileyo. uvavanyo kunye nolawulo lomgangatho. Ukuqonda ukuntsonkotha kokwenziwa kweRogers PCB kuqaqambisa ukhathalelo, ukuchaneka, kunye nobuchule obubandakanyekayo ekwenzeni ezi bhodi zisebenza kakhulu.
