Momwe mungathetsere vuto la PCB bolodi laminate yamkuwa

Nazi zina mwazovuta kwambiri kukumana PCB dera bolodi mavuto ndi mmene kutsimikizira iwo. Mukakumana PCB laminate mavuto, muyenera kuganizira kuwonjezera kwa PCB laminate mfundo zakuthupi. Zotsatirazi akufotokoza mmene kuthetsa vuto la PCB dera bolodi mkuwa atavala laminate?

PCB dera bolodi mkuwa atavala laminate vuto limodzi. Kuti athe kufufuza ndi kupeza

N’zosatheka kupanga nambala iliyonse ya matabwa PCB dera popanda kukumana ndi mavuto, amene makamaka amati zinthu za PCB mkuwa atavala laminate. Pamene mavuto khalidwe zimachitika kwenikweni kupanga ndondomeko, zikuoneka kuti nthawi zambiri chifukwa PCB gawo lapansi zinthu kukhala chifukwa cha vuto. Ngakhale kulembedwa mosamalitsa ndi kugwiritsiridwa ntchito kwa PCB laminate ukadaulo sakunena zinthu zoyeserera zomwe ziyenera kuchitidwa kuti zitsimikizire kuti PCB laminate ndiye chifukwa cha zovuta zopanga. Nazi zina mwazovuta kwambiri zomwe zimakumana ndi PCB laminate ndi momwe mungadziwire.

Mukakumana PCB laminate mavuto, muyenera kuganizira kuwonjezera kwa PCB laminate mfundo zakuthupi. Nthawi zambiri, ngati ukadaulo uwu sunakwaniritsidwe, zipangitsa kuti zinthu zisinthidwe mosalekeza ndipo izi zimapangitsa kuti zinthu ziwonongeke. Nthawi zambiri, zovuta zakuthupi zomwe zimabwera chifukwa cha kusintha kwa mawonekedwe a PCB laminates zimachitika muzinthu zopangidwa ndi opanga pogwiritsa ntchito magulu osiyanasiyana azinthu zopangira kapena kugwiritsa ntchito kukanikiza kosiyanasiyana. Ogwiritsa ntchito ochepa omwe ali ndi zolemba zokwanira kuti athe kusiyanitsa katundu wokakamiza kapena magulu azinthu pamalo opangira. Chifukwa chake, nthawi zambiri zimachitika kuti ma PCB amapangidwa mosalekeza ndikuyikidwa ndi zigawo, ndipo ma warps amapangidwa mosalekeza mu thanki ya solder, yomwe imawononga ntchito zambiri komanso zida zodula. Ngati nambala ya batch ya zinthu zotsitsa zitha kupezeka nthawi yomweyo, wopanga laminate wa PCB akhoza kutsimikizira nambala ya batch ya utomoni, nambala ya batch ya zojambulazo zamkuwa, ndi kuzungulira kwa machiritso. Mwa kuyankhula kwina, ngati wogwiritsa ntchito sangathe kupereka kupitiriza ndi kayendetsedwe ka khalidwe la PCB laminate wopanga, izi zidzachititsa kuti wogwiritsa ntchitoyo awonongeke kwa nthawi yaitali. Zotsatirazi zikuwonetsa zambiri zokhudzana ndi zida zapansi panthaka pakupanga ma board a PCB.

PCB dera bolodi mkuwa atavala laminate vuto awiri. Vuto pamwamba

Zizindikiro: kusamata kosindikiza bwino, kusamata bwino kwa plating, magawo ena sangathe kuzikika, ndipo mbali zina sizingagulitsidwe.

Njira zowunikira zomwe zilipo: nthawi zambiri zimagwiritsidwa ntchito popanga mizere yowonekera pamadzi pamwamba pa bolodi kuti awonere:

chifukwa chotheka:

Chifukwa chapamwamba kwambiri komanso chosalala chopangidwa ndi filimu yotulutsidwa, mkuwa wosatsekedwa ndi wowala kwambiri.

Kawirikawiri pambali yopanda chitsulo ya laminate, wopanga laminate samachotsa wotulutsa.

Mitsempha ya zojambulazo zimapangitsa kuti utomoni utuluke ndikuwunjikana pamwamba pa zojambulazo. Izi nthawi zambiri zimachitika pazithunzi zamkuwa zomwe zimakhala zowonda kuposa 3/4 ounce kulemera kwake.

Wopanga zojambula zamkuwa amavala pamwamba pa zojambulazo zamkuwa ndi ma antioxidants ochulukirapo.

Wopanga laminate adasintha utomoni, kuvula zoonda, kapena kupukuta.

Chifukwa cha ntchito yolakwika, pali zidindo zambiri zala kapena madontho amafuta.

Dikirani ndi mafuta a injini panthawi yokhomerera, osalemba kanthu kapena kubowola.

Njira zothetsera mavuto:

Musanayambe kusintha pakupanga laminate, gwirizanani ndi wopanga laminate ndikutchula zinthu zoyeserera za wogwiritsa ntchito.

Ndibwino kuti opanga laminate amagwiritsa ntchito mafilimu ngati nsalu kapena zipangizo zina zotulutsa.

Lumikizanani ndi wopanga laminate kuti ayang’ane gulu lililonse lazojambula zamkuwa zomwe zili zosayenera; funsani njira yoyenera yochotsera utomoni.

Funsani wopanga laminate njira yochotsera. Changtong amalimbikitsa kugwiritsa ntchito hydrochloric acid, ndikutsuka ndi makina kuti muchotse.

Lumikizanani ndi wopanga laminate ndikugwiritsa ntchito makina kapena njira zochotsera mankhwala.

Phunzitsani ogwira ntchito m’njira zonse zobvala magolovesi kuti azigwira zotchingira zamkuwa. Pezani ngati laminate imatumizidwa ndi pad yoyenera kapena yodzaza m’thumba, ndipo padiyo imakhala ndi sulfure yochepa, ndipo thumba loyikamo lilibe dothi. Samalani kuti palibe amene akuchigwira mukamagwiritsa ntchito chotsukira chokhala ndi silicone chokhala ndi Copper chojambula.

Chotsani ma laminate onse musanayambe plating kapena kutengerapo ndondomeko.
