Munyika yemagetsi nemaseketi, mabhodhi edunhu akadhindwa (PCBs) anoita basa rakakosha mukubatanidza nekusimbisa zvikamu zvakasiyana. Kubatanidza mabhodhi maviri ePCB itsika yakajairika, kunyanya kana uchigadzira masisitimu akaomarara kana kuwedzera kushanda. Mune ino blog, isu tinokutungamira iwe kuburikidza nemaitiro ekubatanidza pasina musono mabhodhi maviri ePCB.
Danho 1: Ziva zvinodiwa zvekubatanidza:
Usati wanyura mukuita, zvakakosha kuona izvo zvinodiwa zvekubatanidza mabhodhi maviri ePCB. Inogona kushandiswa kuwedzera kushanda, kugadzira maseketi makuru, kana kungofambisa kutaurirana pakati pemabhodhi maviri. Kunzwisisa uku kuchatitungamirira pakusarudza nzira yakakodzera yekubatanidza.
Danho 2: Sarudza nzira yekubatanidza:
Pane nzira dzakawanda dzekubatanidza mabhodhi maviri ePCB. Ngationgororei dzimwe sarudzo dzakajairika:
1. Welding:
Soldering ndiyo inonyanya kushandiswa nzira yekubatanidza PCB mabhodhi. Zvinosanganisira kupa kubatanidza magetsi nekunyungudutsa simbi alloy (solder) kugadzira chisungo chakasimba pakati pemapadhi emhangura emapuranga maviri. Ita shuwa yekuigadzirisa zvakanaka uye shandisa simbi yekunyungudutsa yekudziya kwayo kune yakavimbika solder joint.
2. Chibatanidza:
Kushandisa zvibatanidza kunopa imwe nzira iri nyore yekubatanidza nekubvisa mabhodhi ePCB. Kune marudzi akasiyana-siyana ekubatanidza pamusika senge misoro, zvigadziko uye tambo dzeribhoni. Sarudza iyo yakakodzera yekubatanidza mhando zvichienderana nezvaunoda chaizvo.
3. Wiring:
Kuti zvibatanidzwe zviri nyore uye zvenguva pfupi, waya dzinogona kushandiswa kubhuroka kubatanidza kunodiwa pakati pePCB board. Vhura magumo ewaya, woapinza ne solder, woabatanidza nemapedhi awo pamapuranga maviri. Iyi nzira inobatsira panguva yeprototyping kana debugging chikamu.
Nhanho 3: Gadzirira bhodhi rePCB:
Usati waenderera nekubatanidza, ita shuwa kuti ese maPCB mabhodhi akagadzirira kubatanidzwa:
1. Chenesa nzvimbo: Shandisa detergent kana isopropyl alcohol kuti ubvise chero tsvina, tsvina yakasara kana oxide kubva pamapadhi emhangura.
2. Gadzirisa chimiro chechikamu: Kana iwe uchida kubatanidza akaungana mabhodhi ePCB, ndapota ita shuwa kuti zvikamu zviri pamapuranga maviri hazvizokanganisa mumwe nemumwe. Rongedza marongerwo kana zvichidikanwa.
Nhanho 4: Shandisa nzira yekubatanidza:
Zvino zvatine nzira yekubatanidza uye PCB board yakagadzirira, ngatitangei kuvabatanidza:
1. Welding nzira:
a. Rongedza bhodhi rePCB nemazvo, kuve nechokwadi chekuti mapedhi emhangura anowirirana akatarisana.
b. Isa shoma shoma padhi kuti ubvise okisidhi uye kusvibiswa.
c. Pisa simbi yakanyungudutswa woibata pajoinhi resolder kuitira kuti solder yakanyunguduka ifambe zvakaenzana pakati pemapedhi. Chenjerera kuti usapisa zvikamu paPCB.
2. Nzira yekubatanidza:
a. Sarudza majoini akakodzera ebhodhi rako uye woaisa zvinoenderana pamaPCB maviri.
b. Ita shuwa kurongeka kwakaringana uye sunda majoini pamwe chete zvakasimba kusvika anyatsosangana.
3. Wiring nzira:
a. Sarudza hukama hunodiwa pakati pemapuranga maviri ePCB.
b. Cheka urefu hwakakodzera hwetambo uye bvisa magumo.
c. Tinning migumo yewaya ne solder inovandudza kubatana kuvimbika.
d. Solder waya yakavharwa inopera kumapedhi anoenderana pane ese maPCB, kuve nechokwadi kurongeka kwakaringana.
Kubatanidza maviri PCB mabhodhi hunyanzvi hwakakosha kune zvemagetsi hobbyists uye nyanzvi. Nekutevera nhanho-ne-nhanho gwara rakapihwa pamusoro uye nekuziva izvo zvinodiwa, unogona kubudirira kugadzira kubatana kwakavimbika pakati pePCB mapuranga. Ingoyeuka kungwarira panguva iyi kuitira kuti urege kukuvadza bhodhi kana zvikamu. Kufara kubatana!
