Sei zvakaoma kuisa tin muPCB pads?

Chikonzero chekutanga:Tinofanira kufunga pamusoro pekuti idambudziko rekugadzira vatengi.Izvo zvinodiwa kuti utarise kana paine nzira yekubatanidza pakati pedhi uye pepa remhangura, izvo zvinozoita kuti kusakwana kwekupisa kwepadhi.

Chikonzero chechipiri:Kana iri dambudziko rekushanda kwevatengi.Kana iyo welding nzira isiriyo, inokanganisa kusakwana kwekupisa simba, tembiricha uye nguva yekubata, izvo zvichaita kuti zviome kuita tin.

Chikonzero chechitatu : kuchengetwa kusina kunaka.

① Mumamiriro ezvinhu akajairwa, iyo tin yekupfapfaidza nzvimbo inozozara oxidized kana kupfupika mukati mevhiki.

② OSP pamusoro pekurapa maitiro anogona kuchengetwa kweinenge mwedzi mitatu.

③ Kuchengetwa kwenguva refu kwendiro yegoridhe.

Chikonzero chechina: flux.

① Chiitiko chacho hachina kukwana kubvisa zvachose oxidizing zvinhu zvePCB pejikana SMD welding chinzvimbo.

② Huwandu hwe solder paste pajoinhi ye solder haina kukwana, uye iyo yekunyorova pfuma yekuyerera mu solder paste haina kunaka.

③ Ini pane mamwe majoini ekutengesa haina kuzara, uye flux nehupfu inogona kunge isina kunyatsosanganiswa isati yashandiswa.

Chikonzero chechishanu: pcb fekitari.

Pane zvinhu zvine mafuta padhi zvisina kubviswa, uye padhi yacho haina kukwizwa oxidized isati yabuda mufekitari.

Chikonzero chechitanhatu: reflow soldering.

Kurebesa preheating nguva kana yakawandisa preheating tembiricha inotungamira mukutadza kwe flux basa.Tembiricha yainge yakadzikira, kana kuti speed yacho yaimhanya, uye rata harina kunyungudika.

Pane chikonzero nei solder pad redunhu bhodhi isiri nyore kuita tin.Kana zvikaonekwa kuti hazvisi nyore kuisa rata, zvinofanirwa kutarisa dambudziko nenguva.

PCBFuture yakazvipira kupa vatengi nemhando yepamusoroPCB uye PCB musangano.Kana iwe uchitsvaga yakakodzera Turnkey PCB gungano mugadziri, ndapota tumira yako BOM mafaera uye PCB mafaera kune sales@pcbfuture.com.Ese mafaera ako akavanzika zvakanyanya.Tichakutumira quote chaiyo ine nguva yekutungamira mumaawa makumi mana nemasere.
