Kune mhando dzakawanda dzePCB redunhu mabhodhi pamusika, uye zvakaoma kusiyanisa pakati pezvakanaka nezvakaipa.Panyaya iyi, heino nzira shoma dzekuziva kunaka kwePCB redunhu mabhodhi.

Tichitarisa kubva pakuonekwa

1. Kuonekwa kwe weld seam

Sezvo pane zvikamu zvakawanda paPCB redunhu bhodhi, kana welding isiri yakanaka, zvikamu zvebhodhi redunhu zvichadonha nyore, zvichikanganisa zvakanyanya kunaka kwekunama uye chitarisiko chebhodhi redunhu, saka zvakakosha kuti uve wakasimba welding.

2. Mitemo yakajairika yehukuru uye ukobvu

Sezvo PCB redunhu mabhodhi ane ukobvu hwakasiyana zvichienzaniswa neakajairwa edunhu mabhodhi, vashandisi vanogona kuyera uye kutarisa zvinoenderana nezvavanoda.

3. Chiedza uye ruvara

Kazhinji yekunze PCB redunhu bhodhi rakafukidzwa neingi yekudzivirira.Kana ruvara rwebhodhi rusina kujeka uye pane inki shoma, zvinoreva kuti bhodhi rekudzivirira pacharo harina kunaka.

Kutonga kubva mundiro zvinhu

1. HB makadhibhokisi akachipa uye ari nyore kukanganisa nekutyoka.Inogona chete kugadzirwa mune imwe panel.The component surface yakasviba yero muruvara uye ine hwema hunokasharara.Iyo copper yemhangura yakaoma uye yakaonda.

2. Single-sided 94V0 uye CEM-1 mabhodhi anodhura zvakanyanya kupfuura kadhibhodhi.Rudzi rwechikamu chepamusoro rakajeka yero.Izvo zvinonyanya kushandiswa kumapuranga emabhizimisi uye mapuranga emagetsi ane zvinodiwa zvekudzivirira moto.

3. Fiberglass board ine mari yakakwirira, simba rakanaka, uye yakasvibira kumativi ose.Chaizvoizvo, mazhinji PCB edunhu mabhodhi anogadzirwa nechinhu ichi.Iyo copper yemhangura inogona kunyatsojeka uye yakanaka, asi iyo unit board inorema.Hazvina mhosva kuti ruvara rweinki rwakadhindwa pabhodhi rePCB redunhu, rinofanira kuva rakatsetseka uye rakatsetseka, uye hapafaniri kuva nemitsara yenhema, yakafumurwa mhangura kana kupupuma.
