The PCB board (Printedcircuitboard) ndi gulu lothandizira lazigawo zamagetsi ndi operekera kulumikizana pakati pa zida zamagetsi ndi zida zamagetsi.Ndi pafupifupi zomangamanga zonse wanzeru zipangizo.Kuphatikiza pa ntchito zoyambira kukonza zida zazing'ono zingapo zamagetsi, ntchito yofunika kwambiri ndikupereka kulumikizidwa kwa zida zamagetsi zomwe zili pamwambapa.
Kodi zigawo za PCB board ndi chiyani?
The PCB dera bolodi makamaka wapangidwa ndi kuwotcherera PAd, kudzera dzenje, dzenje okwera, waya, zigawo zikuluzikulu, zolumikizira, kudzazidwa, malire magetsi ndi zina zotero.
(1) Pad: dzenje zitsulo ntchito kuwotcherera zikhomo zigawo zikuluzikulu.
(2) Kupyolera mu mabowo: pali zitsulo kudzera m'mabowo ndi zopanda zitsulo kupyolera m'mabowo, momwe zitsulo kudzera m'mabowo zimagwiritsidwa ntchito kugwirizanitsa zikhomo za zigawo pakati pa wosanjikiza uliwonse.
(3) Bowo lokwera: lomwe limagwiritsidwa ntchito kukonza bolodi ladera.
(4) Kondakitala: magetsi network mkuwa filimu ntchito kulumikiza zikhomo zigawo zikuluzikulu.
(5) Zolumikizira: zigawo zomwe zimagwiritsidwa ntchito polumikiza matabwa ozungulira.
(6) Kudzaza: kugwiritsa ntchito mkuwa kwa maukonde a waya pansi kumatha kuchepetsa kutsekeka.
(7) Malire amagetsi: amagwiritsidwa ntchito kudziwa kukula kwa bolodi la dera, zigawo za bolodi sizingadutse malire.
PCB dera bolodi malinga ndi dongosolo akhoza kugawidwa mu PCB gulu limodzi, PCB awiri gulu, PCB multilayer bolodi;Common multilayer bolodi ndi zinayi, asanu wosanjikiza bolodi, zovuta pcb multilayer bolodi akhoza kufika zigawo zoposa khumi.
The zigawo zambiri za matabwa PCB, m'pamenenso khola ndi odalirika ntchito magetsi, ndi apamwamba mtengo.Kusiyana kwa mtengo wa mapanelo amodzi ndi awiri sikuli kwakukulu.Ngati palibe chofunikira chapadera, mafakitale onse amasankha mapanelo awiri.Kupatula apo, magwiridwe antchito ndi kukhazikika kwa gulu lapawiri ndikwabwino kuposa gulu limodzi.
Mu PCB multilayer bolodi, tsopano makampani ndi ambiri ntchito kapena anayi, asanu wosanjikiza bolodi, ogula zamagetsi makampani ndi apamwamba mlingo pcb bolodi ndi zambiri.Ngakhale mapanelo a multilayer ali ndi zabwino zambiri kuposa mapanelo apawiri pakuchita, kukhazikika, phokoso ndi zina, mabizinesi ambiri ndi mainjiniya amakondabe mapanelo apawiri kuti aganizire zamtengo.
Pamene zipangizo zanzeru zikuchulukirachulukira, zowonjezera zowonjezera zimafunikira, zomwe zimatsogolera ku mabwalo ochulukirapo ndi zowonjezera pa PCB.Pa nthawi yomweyo, zofunika khalidwe mkulu panopa PCB zolumikizira bolodi nawonso bwino.Small kukula PCB bolodi sangangochepetsa mtengo, komanso mosavuta kamangidwe ka bolodi PCB, kotero kuti imfa dera kufala chizindikiro ndi ang'onoang'ono.
Chojambulira chapamwamba cha PCB chamakono chimangokhala kukula kwa knuckle, ndipo cholumikizira cholumikizira ndi siliva chokutidwa ndi mkuwa wofiyira, womwe umathandizira kwambiri magwiridwe antchito apano a cholumikizira.Ngakhale kukula yaing'ono akhoza kukhala mkulu panopa kunyamula, kuonetsetsa kuthamanga yosalala wa dera, ndi njira zosiyanasiyana unsembe akhoza kukwaniritsa unsembe zosowa zosiyanasiyana makasitomala a PCB bolodi.
Amass ali ndi utali wosiyanasiyana wolumikizira ma board a PCB amitundu yosiyanasiyana, omwe amagwirizana ndi makulidwe apakati a 1.0-1.6mm kuti atsimikizire kugwiritsa ntchito bwino zida!
