Huremu hweMhangura yePCB Kugadzira: Nhungamiro Yekutanga

Mabhodhi edunhu akadhindwa (PCBs) chikamu chakakosha chemagetsi emazuva ano.Ivo vanoshanda semusana wezvigadzirwa zvemagetsi, vachipa chikuva chekubatana kwezvikamu zvemagetsi.Mhangura inyanzvi yemagetsi conductor uye inoshandiswa zvakanyanya mukugadzira PCB.

Mukugadzira nzira yePCB, huremu hwemhangura hunoita basa rakakosha.Huremu hwemhangura zvinoreva kukora kana kuwanda kwemhangura inoiswa pamusoro pebhodhi redunhu.Huremu hwemhangura hunoshandiswa mukugadzira PCB hunokanganisa zvakananga magetsi uye michina yebhodhi.Mune ino blog, isu tichaongorora akasiyana masimbi emhangura anoshandiswa mukugadzira PCB uye kukosha kwawo.

Kunzwisisa Huremu hweCopper muPCB Kugadzira

Huremu hwemhangura hunowanzoyerwa mumaounces paskweya tsoka (oz/ft²).Iyo inonyanya kushandiswa huremu hwemhangura muPCB kugadzira kubva pa0.5 oz/square tsoka (17 µm) kusvika 3 oz/square tsoka (105 µm).Zviyereso izvi zvinotarisa ukobvu hwemhangura hwezvikamu zvekunze zvePCB, zvidimbu zvemukati, uye maburi emhangura.

Kusarudzwa kwehuremu hwemhangura kunoenderana nezvinhu zvakadai sezvinodiwa magetsi ekushanda, simba remagetsi uye mari.Ngatiitei

tarisa zvakadzama pazviremu zvemhangura zvakasiyana uye mashandisiro azvo mukugadzira PCB.

1. 0.5 oz/ft2 (17 µm) Huremu hweMhangura:
Ichi ndicho huremu hwemhangura hwakareruka hunoshandiswa mukugadzira PCB.Inowanzo shandiswa mune akareruka uye akareruka PCB maapplication.Aya mapuranga anowanzo shandiswa mumagetsi evatengi apo mutengo uye uremu zvinonyanya kufunga.Zvisinei, kuderedzwa kwemhangura yemhangura kunokanganisa kukwanisa kutakura mafungu akakwirira uye kunogona kukonzera kuwedzera kwekudzivirira.

2. 1 oz/square tsoka (35 µm) huremu hwemhangura:
Iyi ndiyo inonyanya kushandiswa huremu hwemhangura mukugadzira PCB.Inobata chiyero pakati pekuita uye mari-inobudirira.maPCB ane 1 oz/sq.ft. uremu hwemhangura hunogona kubata mhepo ine mwero uye yakakodzera kune zvakasiyana-siyana zvekushandisa, kusanganisira telecommunication, motokari uye maindasitiri emagetsi.

3. 2 oz/square tsoka (70 µm) huremu hwemhangura:
Sezvo kudiwa kwepamusoro kutakura kugona kunowedzera, maPCB ane huremu hwemhangura hwe2 ounces/square tsoka inova yakakosha.Anozivikanwa nekunatsiridza kupisa kwawo, mabhodhi aya anowanzoshandiswa mumagetsi emagetsi, maamplifiers emagetsi, UPS masisitimu uye mamwe maapplication anoda simba razvino rekutakura.

4. 3 oz/ft2 (105 µm) Huremu hweMhangura:
MaPCB ane huremu hwemhangura hwemaonzi matatu paskweya tsoka anoonekwa semapuranga anorema emhangura.Aya mabhodhi anoshandiswa mumashandisirwo anoda hukuru hwekutakura huripo huripo kana nani kupisa kupisa.Mimwe mienzaniso inosanganisira masisitimu ekugovera magetsi, majaja ebhatiri epamusoro-azvino, uye ma controller mota.

Kukosha Kwehuremu hweMhangura muPCB Manufacturing

Kusarudza huremu hwakakodzera hwemhangura kwakakosha pakuita PCB kuita uye kuvimbika.Heano zvimwe zvakakosha zvinoratidzira kukosha kwehuremu hwemhangura:

1. Kuita kwemagetsi:
Huremu hwemhangura hunotaridza kugona kwePCB kutakura ikozvino pasina kugadzira kuramba kwakanyanya.Kusakwana kwemhangura ukobvu kunogona kukonzera kuramba kukwira, zvichikonzera kudonha kwemagetsi uye kupisa kwebhodhi.Kune rumwe rutivi, huremu hwemhangura hwepamusoro hunobvumira kubata zviri nani ikozvino uye kuderera kwekudzivirira.

2. Mechanical simba:
Pamusoro pekuve nemagetsi conductive, mhangura inopawo mechanical kusimbisa kuPCB.Huremu hwemhangura hwakakodzera hunowedzera simba uye kusimba kubhodhi redunhu, richiibvumira kuramba kukotama, kuputika, kana kumwe kushushikana kwemuviri.

3. Kutarisira kupisa:
Mhangura ndiyo yakanaka conductor yekupisa.Huremu hwemhangura hwakakwana hunobatsira kubvisa zvinopisa kupisa kunogadzirwa nezvikamu zvakaiswa paPCB.Izvi zvinodzivirira kushushikana kwekupisa kana kutadza kwechikamu nekuda kwekupisa, kuve nechokwadi chekugara kwenguva refu uye kuvimbika kwebhodhi.

4. Tsananguro yehupamhi uye nzvimbo:
Huremu hwemhangura hunokanganisa hupamhi hwekutsvaga uye nhungamiro yepakati panguva yePCB dhizaini uye dhizaini.Huremu hwemhangura hwepamusoro hunoda hupamhi hwekutsvagira hurefu uye nzvimbo kuti ibvumidze kuyerera kwazvino uye kudzivirira kukwira kwakanyanya.

Mukupedzisa

Muchidimbu,kusarudza huremu hwemhangura hwakakodzera kwakakosha pakugadzira yakakwira-inoshanda uye yakavimbika PCB.Sarudzo inoenderana nezvinodiwa chaizvo zvechikumbiro, uchifunga nezvekuita kwemagetsi, mechanical simba uye thermal management zvinodiwa.Kunyangwe iri lightweight mutengi zvemagetsi kana akakwira-simba maindasitiri maapplication, huremu hwemhangura hunoita basa rakakosha mukugadzira PCB uye hunofanirwa kutariswa zvakanyanya panguva yekugadzira chikamu.
