PCB silikaKusindikiza ndi njira yofunika pakupanga ma boloni a madera a PCB, omwe amatsimikizira mtundu wa mabokosi a PCB. Kapangidwe ka madera a PCB ndi kovuta kwambiri. Pali zambiri zazing'ono popanga. Ngati sichinagwiritsidwe ntchito moyenera, chidzakhudza magwiridwe antchito onse a PCB. Kuti muwonjezere luso la kapangidwe kake ndi mtundu wazogulitsa, kodi tiyenera kuganizira nkhani iti popanga?
Zithunzizi zimapangidwa pa bolodi la PCB ndi silika wosindikiza kapena kusindikiza. Chilichonse chimayimira gawo lina ndipo limagwira gawo lofunikira kwambiri pakupanga pambuyo pake.
Ndiloleni ndiyambitse anthu wamba. Nthawi zambiri, Cimirani capocator, r amayima otsutsa, l amayima a transtator, y imayimira chinsinsi, k amayima a buzrsistator, y amayima a diider, y amayimatu, y amayima a Dristal, y amayimatu za crystator, y amayima a Dristal, y amayimatu za ma cryrutor, y amayima a Dristal, Y amayimilira a buzrder, k amayima a diider, y amayimatu, y amayima a Dridetor, y amayima a Dristal, y amayima a Dridetor, y amayimatu za ma crystator, y amayimatu, y amayima a Dridetor, Y amayimilira a buzrder, k amayima a buzrsistor, y amayimatu za crystator, y amayima a Drystator, y amayimatu za crystator, y amayima pa Cirry
Pa boloding, nthawi zambiri timaona ziwerengero monga R101, C203, ndi zina zowonjezera, nambala yachinayi ndi yachinayi ikuyimira nambala ya madera. Chifukwa chake timamvetsetsa bwino kuti R101 ndiye wotsutsa woyamba wa madera ogwirira ntchito, ndi C203 ndiye katswiri wachitatu padera lachiwiri la ntchito, kuti chizindikiritsochi ndi chosavuta kumva.
M'malo mwake, otchulidwa pa bolodi la madera a PCB ndi zomwe nthawi zambiri timatchulanso chophimba silika. Chinthu choyamba ogula amawona akapeza bolodi ya PCB ndi cholembera chosalala pa icho. Kudzera mwa zilembo za silika, amatha kumvetsetsa bwino zomwe zigawo zikuluzikulu ziyenera kuyikidwa pamalo aliwonse mukakhazikitsa. Zosavuta kusonkhanitsa chigamba ndi kukonza. Ndiye ndi mavuto ati omwe amayenera kuyang'aniridwa pazinthu zopangira silika?
1) Mtunda pakati pa silika ndi pad: Screen Screen siyingayikidwe pad. Ngati padyo imakutidwa ndi silika ya silika, idzakhudzanso ntchito yazinthu, kotero kutalika kwa 6-8mil kuyenera kusindikizidwa. Ngati mzerewu mulifupi kwambiri, inki siyingatuluke pazenera losindikiza, ndipo zilembo sizingakhale zosindikizidwa kutalika kwa silika: kutalika kwake nthawi zambiri kumakhala pamwamba pa 0.6mm (25mil). Ngati kutalika kwake kuli kochepera 25mil, otchulidwa osindikizidwa sakhala osamveka komanso opanda matupi. Ngati mzerewo ndi wandiweyani kapena mtunda uli pafupi kwambiri, umayambitsa br.
4) Malangizo a kusindikiza kwa silika: nthawi zambiri amatsatira mfundo ya kumanzere kupita kumanja ndi pansi mpaka pamwamba.
5) Polarity Tarition: Zigawo zikuluzikulu zimakhala ndi polario. Mapangidwe osindikiza a Screen ayenera kulankhulira polemba mitengo yabwino komanso yolakwika komanso zinthu zina. Ngati mitengo yotsimikizika ndi yolakwika imasinthidwa, ndikosavuta kuyambitsa dera lalifupi, ndikupangitsa kuti mabizinesi aziwotcha ndipo sangaphimbe.
6) chizindikiritso chizithunzi: chizindikiritso chizindikiritso chimatha kusiyanitsa chitsogozo cha zigawo. Ngati zilembo za silika zimayambitsa chizindikiritso molakwika kapena palibe chizindikiritso, ndizosavuta kupangitsa zinthuzo kuti zitheke.
7) Malo a Silk Screen: Osayika kapangidwe ka silika pa bowo lobowola, apo ayi bolodi ya PCB idzakhala ndi zilembo zosakwanira.
Pali zojambula zambiri ndi zofunikira za kapangidwe kaloze kalonga, ndipo ndi izi zomwe zimalimbikitsa kukula kwaukadaulo wosindikiza PCB.
