Nzira yekudzivirira sei zviitiko zvitanhatu zvetini kubatanidza pane circuit board mushure mekutsvaira kwesimbi.

1. Nekuda kwechiitiko chekubatana kwetini kunokonzerwa neyakareba chikamu pini panguva yekuzunguzirwa kwesimbi kwedunhu bhodhi, kutariswa kuchabhadharwa kuwedzere kureba kwechikamu pini kazhinji 1.5-2mm, iyo isingazoitika kana ikasadarika kukwirira uku. .

2. Nekuti iyo PCB maitiro dhizaini inowedzera uye yakaoma uye pini yekumisikidza iri kuwanda uye kuwanda, iko kuitika kwetini yekubatanidza mushure mekusungurudza kwe wave kunoitika. Kuchinja iyo padhi dhizaini ndiyo mhinduro. Semuenzaniso, kudzikisa padhi saizi, kuwedzera hurefu hwepadhi ichibuda padivi remasaisai, kuwedzera iyo flux chiitiko / kudzora iyo yekuwedzera yekuwedzera urefu zvakare mhinduro.

3. Mushure mekusungirirwa kwemasaisai, tini yakanyungudika inopinda pamusoro pebhodhi redunhu kuti riumbe kubatana kwetini pakati pembiru dzechinhu. Chikonzero chikuru chechiitiko ichi ndechekuti dhayamita yemukati yepad isina chinhu yakakura kwazvo, kana dhayamita yekunze yepini yechinhu chacho ishoma kwazvo.

4. Iyo wave crest inoumbwa nedhivhosi tsoka tsoka mune mbiri nzvimbo dzakabatana netini mushure mewelding.

5. Wave soldering netini nekuda kwekuwandisa kwepad saizi.

6. Kubatana kweTini yezvipini zvinoriumba mushure mekusungirirwa kwemafungu nekuda kwekushomeka kwekutengesa kwezvipini.

Nzira yekudzivirira tini kubatanidza wedunhu bhodhi mushure mekuzunguzirwa soldering.

1. Dhizaini zvinoenderana nePCB dhizaini dhizaini. Iyo refu axis yemaviri magumo machipisi ichave akaenzana kune iyo yekutenderera nzira, uye iyo yakareba axis yeSOT neSOP ichave yakafanana neiyo yekutenderera nzira. Wedzera padhi yepini yekupedzisira yeSOP (dhizaina padhizaini);

2. Iyo pini yezvinhu zvakaisirwa zvinoumbwa zvinoenderana nemakomba maspace uye gungano zvinodikanwa zvebhodhi rakadhindwa. Kana iyo pfupi yekuisa nzira yekumonera ikatambirwa, chikamu chemapini pane chekumusoro chemberi chichafumurwa kumeso kwebhodhi rakadhindwa ne0.8 ~ 3mm, uye chikamu chemuviri chinenge chakamira panguva yekuiswa;

3.Gadza iyo preheating tembiricha maererano nePCB saizi, kungave kune multilayer mabhodhi, huwandu hwezvinhu, huwandu hwezvinhu zvakaiswa, nezvimwe;

4. Iyo tini wave tembiricha ndeye 250 ± 5 ℃, uye iyo nguva yekutenderera iri 3 ~ 5S. Kana tembiricha yakadzikira zvishoma, kumhanyisa kwebhandi rekutakura kunofanira kudzikira;

5. Tsiva kuyerera.
