Kwinkqubo yokwenziwa kwe-PCB, siyakhubekisa ukucetyiswa ukuba silize i-PCB njenge-tab-routing ukujongana neebhodi zethu edge.apha siza kukunika ingcaciso eneenkcukacha yenkqubo yokubonisa ithebhu.
Yintoni indlela yethebhu?
Indlela yeTab yindlela ethandwayo yokwenziwa kwepaneli yePCB esebenzisa iithebhu ezinemibhobho okanye engenazo.Ukuba wahlula ii-PCB ezinephaneli ngesandla, kufuneka usebenzise uhlobo olunemingxuma.Ukuba uvakalelwa kukuba ukwaphula iPCB kwiphaneli kunokubangela uxinzelelo olukhulu kwiPCB, kububulumko ukusebenzisa isixhobo esikhethekileyo esiya kuthintela umonakalo webhodi.
Xa ibhodi inemilo engaqhelekanga, okanye ibhodi idinga i-eddge ecacileyo ke ipaneli kufuneka ifakwe kwithebhu.Umzobo we-8 ubonisa umzobo we-tab-umzila wephaneli, i-Fig 9 yifoto ye-tab -iphaneli yomzila.Kwiphaneli ye-tab-routing ukwenzela ukwaphula ibhodi kwindawo yolawulo emva kokuhlanganisana, inqaku le-V okanye "imingxuma yokuluma imouse" ingasetyenziswa.Imingxuma yokulunywa yimpuku ngumgca wemingxuma esebenza ngendlela efanayo nemingxuma kuluhlu lwezitampu.Kodwa khumbula inqaku le-V liya kunika i-edge ecacileyo emva kokuba iibhodi ziqhekeke kwiipaneli, "imingxuma yokuluma i-mouse" ayiyi kunika umgca ocacileyo.
Kutheni le nto kufuneka sibeke iibhodi njenge-tad-routing?
Enye yeenzuzo ze-tab-routing kukuba unokuvelisa iibhodi ezingezonxande.Ngokwahlukileyo, ukungonakali kwe-tab-routing kukuba kufuna izinto ezongezelelweyo zebhodi, ezinokunyusa iindleko zakho.Kananjalo inokubeka uxinzelelo ngakumbi ebhodini kufutshane nethebhu.Ukuthintela uxinzelelo lwebhodi, kunqanda ukubeka iinxalenye zePCB kufutshane kakhulu neethebhu.Ngelixa kungekho mgangatho ukhethekileyo wokubeka iinxalenye kufutshane neethebhu, xa sithetha ngokubanzi, i-100 mils ngumgama oqhelekileyo.Ukongeza, kunokufuneka ubeke iinxalenye ngaphezulu kwe-100 mils yeePCB ezinkulu okanye ezityebileyo.
Ungazisusa ii-PCB kwiiphaneli phambi okanye emva kokuba zidityanisiwe.Ekubeni iiphaneli zePCB zenza kube lula ukuhlanganisana, eyona ndlela iqhelekileyo kukukhupha iiPCBs emva kokuba indawo yolawulo idityanisiwe.Nangona kunjalo, kufuneka usebenzise inkathalo eyongezelelweyo xa ususa iiPCB kwiiphaneli emva kokuba zidityanisiwe.
Ukuba awunaso isixhobo esikhethekileyo PCB ukususa, kufuneka uthathele ingqalelo ekhethekileyo xa ususa PCBS kwiqela lenjongo.Musa ukugoba!
Ukuba ubunokwaphula i-PCB kwiqela lenjongo ngaphandle kokhathalelo, okanye nokuba amalungu asondele ngokugqithisileyo kwiithebhu, unokufumana umonakalo wamalungu.Ukongeza, i-solder joint ngamanye amaxesha igqabhuka, enokubangela iingxaki kamva.Kukhethwa ukusebenzisa isixhobo sokusika ukususa iiPCB ukunqanda ukugoba ibhodi.
I-PHILIFAST izinikele kwimveliso ye-PCB iminyaka emininzi, kwaye ijongane nemiphetho ye-PCB kakuhle.Ukuba kukho nayiphi na ingxaki kwiiprojekthi zakho ze-PCB, vele ujike kwiingcali kwi-PHILIFAST, ziya kukunika iingcebiso zobuchule.
