I-6 Layer ENIG Impedance Control Heavy Copper PCB
Imisebenzi Ye-Heavy Copper PCB
I-PCB yethusi esindayo inemisebenzi engcono kakhulu yokunweba, ayinqunyelwe izinga lokushisa lokucubungula, indawo ephakeme yokuncibilika ingasetshenziswa ukuvunguza komoya-mpilo, izinga lokushisa eliphansi endaweni efanayo ye-brittle kanye nokunye ukushisela okuncibilika okushisayo, kodwa futhi nokuvimbela umlilo, kungokwezinto ezingashi. .Ngisho nasezimweni zomoya ezidle kakhulu, amashidi ethusi akha ungqimba oluqinile, olungenabuthi oluvikelayo.
Ubunzima Ekulawuleni Machining Of Heavy Copper PCB
Ukuqina kwe-PCB yethusi kuletha uchungechunge lobunzima bokucubungula ekucutshungulweni kwe-PCB, njengesidingo sokunamathisela okuningi, ukugcwaliswa kwepuleti lokucindezela okwanele, ukubhoboza iphedi lokushisela ungqimba lwangaphakathi, ikhwalithi yodonga lwembobo kunzima ukuyiqinisekisa nezinye izinkinga.
1. Izinkinga zokuqinisa
Ngokukhula kokuqina kwethusi, ukuguguleka kwecala kuzoba kukhulu kakhulu ngenxa yobunzima bokushintshaniswa kwe-potion.
2. Ubunzima be-laminating
(1) ngokwanda kwethusi eliwugqinsi, imvume yomugqa omnyama, ngaphansi kwezinga elifanayo lethusi elisele, inani lokugcwalisa i-resin kufanele lenyuke, khona-ke udinga ukusebenzisa ukuphulukisa okungaphezu kweyodwa nengxenye ukuhlangabezana nenkinga yokugcwalisa: isidingo sokwandisa imvume yomugqa wokugcwalisa i-resin, ezindaweni ezifana nokuqukethwe kwerabha kuphezulu, i-resin ephulukisa i-liquid half piece yenza i-laminate yethusi esindayo yisinqumo sokuqala.Ishidi le-semi-cured ngokuvamile likhethwa ku-1080 no-106. Emklamo wongqimba lwangaphakathi, amaphuzu ethusi namabhulokhi ethusi abekwa endaweni engenakhothusi noma endaweni yokugcina yokugaya ukuze kukhuliswe izinga lethusi elisele futhi kuncishiswe ingcindezi yokugcwalisa iglue. .
(2) Ukwanda kokusetshenziswa kwamashidi ahlanganiswe kancane kuzokwandisa ubungozi bama-skateboard.Indlela yokwengeza ama-rivets ingamukelwa ukuqinisa izinga lokulungisa phakathi kwamapuleti ayisisekelo.Njengoba ubukhulu bethusi buba bukhudlwana futhi bukhudlwana, i-resin nayo isetshenziselwa ukugcwalisa indawo engenalutho phakathi kwamagrafu.Ngenxa yokuthi ubukhulu bekhopha obuphelele be-PCB yethusi esindayo ngokuvamile bungaphezu kuka-6oz, ukufana kwe-CTE phakathi kwezinto zokwakha kubaluleke kakhulu [njenge-CTE yethusi ingu-17ppm, indwangu ye-fiberglass ingu-6PPM-7ppm, i-resin ingu-0.02%.Ngakho-ke, ohlelweni lokucutshungulwa kwe-PCB, ukukhethwa kwama-fillers, i-CTE ephansi kanye ne-T high PCB kuyisisekelo sokuqinisekisa ikhwalithi yethusi esindayo (amandla) PCB.
(3) Njengoba ukushuba kwethusi ne-PCB kwanda, ukushisa okwengeziwe kuyodingeka ekukhiqizeni i-lamination.Izinga lokushisa langempela lizohamba kancane, isikhathi sangempela sesigaba sokushisa esiphezulu sizoba sifushane, okuzoholela ekwelapheni kwe-resin okwanele kweshidi le-semi-cured, ngaleyo ndlela kuthinte ukuthembeka kwepuleti;Ngakho-ke, kuyadingeka ukwandisa ubude besigaba sokushisa okuphezulu kwe-laminated ukuze kuqinisekiswe umphumela wokuphulukisa weshidi le-semi-cured.Uma ishidi semi-welashwa alanele, kuholela isamba esikhulu glue ukususwa isihlobo core plate semi-welashwa ishidi, kanye ukwakheka isitebhisi, bese imbobo ukuphuka yethusi ngenxa umphumela ukucindezeleka.
