Chii chinokonzera dema PCBA redunhu bhodhi welding ndiro?

PCBA redunhu bhodhi welding dhisiki dambudziko rakawanda rinowanzoitika redunhu bhodhi rakashata, zvichikonzera PCBA welding disc dema nekuda kwezvikonzero zvakawanda, asi kazhinji zvichikonzerwa nezvikonzero zvinotevera:

1, pad oxidation: Kana iyo PCBA padhi yakafumurwa kune hunyoro kwenguva yakareba, ichaita kuti pamusoro pepadhi iite oxidize, ichigadzira firimu reoxide pamusoro pedhi, zvichikonzera dema, saka, kana uchichengeta PCBA, kutarisisa kunofanirwa kubhadharwa kuchengetedza nharaunda yakaoma, uye panguva imwe chete, PCBA inofanira kuvharwa nenguva kuti irege kuratidzwa kwayo kwenguva refu kumhepo!

2, welding process matambudziko: mune reflow welding kana wave soldering, kana tembiricha yewelding yakakwira zvakanyanya kana nguva yewelding yakarebesa, zvinozotungamira kune oxidation yewelding pad dema chiitiko, kuita uku kunowanzo kukonzerwa nekukuchidzira. tembiricha inodarika iyo inokurudzirwa tembiricha yemhando ye solder, zvichikonzera kukurumidza oxidation process, saka mukuita welding kunofanirwa kuenderana nemaitiro ekushanda e welding!

3, solder dambudziko: solder kazhinji inoreva solder paste, tini, solder unhu zvakanaka kana zvakaipa, kana kushandiswa murombo quality solder, kuchaitawo solder muzvinhu zvinokuvadza uye tsvina yakasunungurwa, zvichiita kuti padhi dema, saka, mukusarudza solder, tinofanira kudzivisa kushandiswa yakaderera-mhando solder!

4, matambudziko ekuchenesa: Kazhinji kutaura, kana iri kushandiswa kwekuyerera kunodiwa kuchenesa bhodhi, kuitira kubvisa iyo inoyerera yakasara padhi, uye kana iyo inoyerera yakasara isina kubviswa zvizere, saka izvi zvakasara zvinoyerera zvinogona kukanganisa. kana carbonize pakupisa kwepamusoro, kuitira kuti padhi ionekwe yakasviba. Naizvozvo, kucheneswa nenguva mushure mekudzikisira kwakakosha!

5, matambudziko echikamu: kana hutano hwezvikamu zvemagetsi zvisina kunaka, kana zvinhu zvepini yepini zvisina kunaka, zvinogonawo kutungamirira kune chiitiko che black welding disc, saka, pakusarudza zvigadzirwa zvemagetsi, tinofanira kusarudza unhu hwakanaka. zvikamu zvekuona kuti hutano hwekuputira uye pini yezvinhu zvezvikamu zvinokodzera.

Icho chiri pamusoro apa ndicho chikonzero chikuru chePCBA welding tray nhema, uye maererano nezvikonzero zvakasiyana-siyana, tinogonawo kusarudza matanho anowirirana ekuvandudza, kuitira kuti tinyatsoderedza dambudziko rePCBA welding tray dema, kuvandudza kunaka kwezvigadzirwa!
