Mtengo wamba wa matabwa osindikizidwa

Mawu Oyamba
Kutengera kapangidwe ka boardboard,mtengo udzasiyana malinga ndi zinthu za bolodi dera, chiwerengero cha zigawo za bolodi dera, kukula kwa bolodi dera, kuchuluka kwa aliyense kupanga, ndondomeko kupanga, osachepera mzere m'lifupi ndi katayanitsidwe mzere, dzenje osachepera. awiri ndi chiwerengero cha mabowo , ndondomeko yapadera ndi zina zofunika kusankha.Pali njira zotsatirazi zowerengera mtengo pamsika:
1. Werengetsani mtengo ndi kukula kwake (kumagwira ntchito pamagulu ang'onoang'ono a zitsanzo)
Wopangayo adzapereka mtengo wagawo pa sentimita imodzi molingana ndi zigawo zosiyanasiyana zamagulu ndi njira zosiyanasiyana.Makasitomala amangofunika kusintha kukula kwa bolodi la dera kukhala ma centimita ndikuchulukitsa ndi mtengo wagawo pa centimita imodzi kuti apeze mtengo wagawo la bolodi lopangidwa..Njira yowerengera iyi ndi yoyenera kwambiri pama board ozungulira aukadaulo wamba, omwe ndi abwino kwa onse opanga ndi ogula.Zotsatirazi ndi zitsanzo:
Mwachitsanzo, ngati wopanga amagula gulu limodzi, zinthu za FR-4, ndi dongosolo la 10-20 masikweya mita, mtengo wake ndi 0.04 yuan/square centimita.Panthawiyi, ngati kukula kwa bolodi la wogula ndi 10 * 10CM, kuchuluka kwa kupanga ndi 1000-2000 chidutswa, kumangokwaniritsa izi, ndipo mtengo wa unit ndi wofanana ndi 10 * 10 * 0.04 = 4 yuan chidutswa.

2. Werengetsani mtengo molingana ndi kukonzanso kwamitengo (yofunikira pazambiri)
Chifukwa zopangira za bolodi lozungulira ndi laminate yamkuwa, fakitale yomwe imapanga laminate ya copper yakhazikitsa miyeso yokhazikika yogulitsa pamsika, wamba ndi 915MM * 1220MM (36 ″ * 48 ″);940MM*1245MM (37″*49″);1020MM*1220MM (40″*48″);1067mm * 1220mm (42″*48″);1042MM*1245MM (41″49″);1093MM*1245MM (43″*49″);wopanga adzakhazikika pa dera kuti atulutsidwe Zinthu, nambala wosanjikiza, ndondomeko, kuchuluka ndi magawo ena a bolodi amagwiritsidwa ntchito kuwerengera kuchuluka kwa magwiritsidwe a laminate yamkuwa ya gulu ili la matabwa ozungulira, kuti awerengere zakuthupi. mtengo.Mwachitsanzo, ngati mutulutsa bolodi la dera la 100 * 100MM, fakitale idzawonjezera kupanga bwino.Itha kusonkhanitsidwa m'magulu akulu a 100 * 4 ndi 100 * 5 kuti apange.Ayeneranso kuwonjezera mipata ndi m'mphepete mwa bolodi kuti athandizire kupanga.Nthawi zambiri, mipata pakati pa ma gong ndi matabwa ndi 2MM, ndipo m'mphepete mwake ndi 8-20MM.Kenako matabwa akuluakulu opangidwa amadulidwa mumiyeso ya zopangira, Ngati zangodulidwa apa, palibe matabwa owonjezera, ndipo kuchuluka kwa ntchito kumakulitsidwa.Kuwerengera magwiritsidwe ntchito ndi sitepe imodzi yokha, ndipo chindapusa chobowola chimawerengedwanso kuti muwone mabowo angati omwe alipo, kukula kwake kwa dzenje laling'ono kwambiri, ndi angati omwe ali m'mabowo akuluakulu, ndikuwerengera mtengo wanjira iliyonse yaying'ono. monga mtengo wa electroplating mkuwa malinga ndi mawaya mu bolodi, ndipo potsiriza kuwonjezera pafupifupi ntchito ndalama, mtengo imfa, phindu mlingo, ndi mtengo malonda a kampani iliyonse, ndipo potsiriza kuwerengera mtengo okwana Gawani ndi chiwerengero cha matabwa ang'onoang'ono amene angathe kupangidwa m'chidutswa chachikulu cha zopangira kuti mupeze mtengo wamagulu a bolodi yaying'ono.Njirayi ndi yovuta kwambiri ndipo imafuna munthu wapadera kuti achite.Nthawi zambiri, mawuwa amatenga nthawi yopitilira maola angapo.

3. Mamita a pa intaneti
Chifukwa mtengo wa matabwa ozungulira umakhudzidwa ndi zinthu zambiri, ogula wamba samamvetsetsa ndondomeko ya quotation ya ogulitsa.Nthawi zambiri zimatenga nthawi yayitali kuti mupeze mtengo, womwe umawononga anthu ambiri komanso zinthu zakuthupi.Mtengo wa komiti yoyang'anira dera, kupereka zidziwitso zaumwini ku fakitale kumabweretsa kuzunza kosalekeza.Makampani ambiri ayamba kupanga pulogalamu yamitengo yamitengo patsamba lawo, ndipo kudzera mu malamulo ena, makasitomala amatha kuwerengera mtengowo momasuka.Kwa omwe satero Anthu omwe amamvetsetsa PCB amathanso kuwerengera mtengo wa PCB mosavuta.
