Kuisa bhodhi redunhu rakadhindwa (PCB) mukati mechivharo inhanho yakakosha mukuona kushanda kwakakodzera uye kuchengetedzwa kwemidziyo yemagetsi.Mune ino blog positi, isu tinotsanangura nhanho dzinodiwa uye nhungamiro yekukubatsira iwe kukwira maPCB munzvimbo dzakavharirwa zvakachengeteka uye nemazvo.
1. Kuronga marongero:
Urongwa hwekungwarira hwekuronga hunofanirwa kudhirowa usati waisa PCB mukati meyakavharirwa.Inosarudza nzvimbo yezvikamu paPCB kuti iwedzere kushandiswa kwenzvimbo mukati mekuvharirwa.Funga nezvehukuru uye chimiro cheyakavharirwa kuti ive nechokwadi chekuti ine mazaru anodiwa kune majoini uye mainterface.
2. Tarisa pakavharirwa:
Nyatsoongorora iyo yakavharirwa kune chero zviratidzo zvekukuvadzwa kana kuremara zvinogona kukanganisa maitiro ekuisa kana PCB mashandiro.Ita shuwa kuti kesi yacho yakachena uye haina chero marara kana zvimwe zvinhu zvekunze zvinogona kukanganisa kuiswa.
3. Gadzirira PCB:
Gadzirira PCB nekuichenesa nemucheka weantistatic kana yemagetsi yekuchenesa.Iva nechokwadi chekuti zvikamu zvose zvakatengeswa zvakanaka uye zvakasimba zvakabatanidzwa kubhodhi.Ongorora kaviri kune chero hukama hwakasununguka kana zvikabudura zvinogona kukonzera matambudziko pakuisa.
4. Isa insulation:
Kudzivirira mapfupi maseketi uye kudzivirira PCB kubva kunyoro kana zvimwe zvakatipoteredza, zvinokurudzirwa kushandisa insulating zvinhu senge nhete yesilicone kana adhesive-backed insulating foam kusvika pasi pePCB.Izvi zvinopawo cushioning uye kudzivirira chero kungangoita kupokana kana vibration pakati pePCB nekesi.
5. Gadzirisa PCB:
Uchishandisa yakakodzera kukwirisa hardware, nyatsoisa PCB munzvimbo yaunoda mukati meyakavharirwa.Zvichienderana nehukuru uye kuoma kwePCB, unogona kushandisa mabhuraketi ekukwira, screws, kana mabhuraketi.Ita shuwa kuti PCB yakasimba, asi chenjerera kuti usapfutidze masiruu nekuti izvi zvinogona kukuvadza PCB kana kusimbisa zvikamu.
6. Gadzira nzvimbo yakakodzera:
Grounding yakakosha kubvisa electrostatic discharge uye kudzivirira kukuvara kwePCB uye zvikamu zvayo.Shandisa tambo yepasi kana tambo yepasi kuti ubatanidze nzvimbo yepasi yePCB kune kesi kuti uve nechokwadi chekuchengetedza uye kuvimbika kwemagetsi.Iyi nhanho inonyanya kukosha kune zvishandiso zvine hunyanzvi hwemagetsi izvo zvinoda kuchengetedzwa kwekuwedzera kubva kuvhiringidzwa yekunze.
7. Muedzo wekukodzera uye basa:
Mushure mekunge PCB yaiswa, ita bvunzo yakakwana kuti uone kukwana kwayo uye kushanda kwayo.Ita shuwa kuti zvese zvinongedzo, ma switch, uye madoko anoenderana nemazaru emumba.Kushanda kuyedzwa kunoitwa kuratidza kuti zvikamu uye iyo yese system inoshanda sezvaitarisirwa.
Kuisa PCB mune yakavharirwa inhanho yakakosha yekugadzira iyo inokanganisa zvakananga kuvimbika uye kuita kwemidziyo yemagetsi.Nekutevera nhanho dzakatsanangurwa mugwaro iri, unogona kukwira PCB nechivimbo uye nemazvo, kuve nechokwadi chekubatanidzwa kwakachengeteka uye kwakanaka mukati mekuvharirwa.Rangarira kuronga marongero, ongorora zvakavharirwa, gadzira PCB, isa insulation, chengetedza PCB, gadza nzvimbo yakakodzera, uye tarisa kuti yakakodzera uye inoshanda.Kutora matanho anodiwa aya kunobatsira iwe kugadzira magungano akasimba, kudzivirira PCB yako, uye kubatsira mukubudirira kwese kweprojekiti yako yemagetsi.
