Maitiro ekuita pcb etching mhinduro kumba

Sezvo tekinoroji ichifambira mberi, kudiwa kwemabhodhi edunhu akadhindwa (PCBs) kuri kuramba kuchikura. PCBs zvinhu zvakakosha mumidziyo yemagetsi inobatanidza zvikamu zvakasiyana-siyana kugadzira maseketi anoshanda. Iyo PCB yekugadzira maitiro inosanganisira akawanda matanho, imwe yematanho akakosha ndeye etching, iyo inotibvumira kubvisa isingakoshi mhangura kubva pamusoro pebhodhi. Nepo kutengeserana etch mhinduro dziri kuwanikwa nyore, iwe unogona zvakare kugadzira yako PCB etch mhinduro kumba. Mune ino blog, tinokutungamirira kuburikidza nekuita, tichikupa zvinodhura uye zviri nyore kushandisa mhinduro kune zvese zvaunoda PCB etching.

raw material:
Kuti ugadzire yekumba PCB etching mhinduro, iwe uchada zvinotevera zvinongedzo:

1. Hydrogen peroxide (3%): Chinhu chakajairika chemumba chinoshanda seanoxidizing agent.
2. Hydrochloric acid (hydrochloric acid): Inowanikwa pazvitoro zvakawanda zve hardware, inonyanya kushandiswa pakuchenesa.
3. Tafura munyu (sodium chloride): Chimwe chinhu chakajairika chemumba chinogona kuwedzera etching maitiro.
4. Mvura yakasvibiswa: inoshandiswa kuderedza mhinduro uye kuchengetedza kuwirirana kwayo.

chirongwa:
Zvino, ngatinyure mukuita kwekugadzira PCB etching mhinduro kumba:

1. Chengetedzo Kutanga: Usati watanga, iva nechokwadi chokuti une midziyo yokudzivirira inodiwa yakadai semagirovhosi, magirazi, uye nzvimbo inofefetera zvakanaka. Makemikari anogona kuva nengozi kana akasabatwa nemazvo, saka chenjerera panguva yese iyi.

2. Mixed solution: Wedzera 100ml hydrogen peroxide (3%), 30ml hydrochloric acid uye 15g munyu mumudziyo wegirazi. Gadzirai musanganiswa zvakanaka kusvikira munyu wapera zvachose.

3. Dilution: Mushure mekusanganisa zvigadziriso zvekutanga, dilue neinenge 300 ml yemvura yakasvibiswa. Iyi nhanho yakakosha pakuchengetedza etch consistency yakanaka.

4. Etching process: Dip the PCB in the etching solution, iva nechokwadi chokuti yakanyura zvachose. Zvinyoro simbisai mhinduro dzimwe nguva kukurudzira etching yakafanana. Nguva yeEtch inogona kusiyana zvichienderana nekuoma uye ukobvu hwematehwe emhangura, asi kazhinji maminetsi gumi kusvika makumi matatu.

5. Shamba uye Uchenese: Mushure menguva yaunoda etching, bvisa PCB kubva kune etching solution uye sukurudza zvakakwana pasi pemvura inoyerera kuti umise etching process. Shandisa bhurashi rakapfava kana chipanje kuchenesa chero tsvina yasara kubva pabhodhi pamusoro.

Kugadzira yako PCB etching mhinduro kumba kunopa inochipa uye iri nyore kushandisa imwe nzira kune zvekutengesa sarudzo. Zvisinei, zvakakosha kuyeuka kuti kushanda nemakemikari kunoda kuchengetedzwa kwakakodzera. Gara uchibata zvinhu izvi munzvimbo ine mhepo yakanaka uye pfeka zvekudzivirira. Homemade PCB etching mhinduro dzinoita kuti DIY zvemagetsi mapurojekiti zvive nyore uku uchichengetedza mari uye kuderedza marara. Saka sunungura hunyanzvi hwako uye unyure munyika yePCB etching kubva mukunyaradza kweimba yako wega!
