SMT simbi mesh inoshandiswa kumvura uye yakasimba mamiriro ekutengesa paste kudhinda paPCB board, redunhu bhodhi mukuwedzera kune bhodhi remagetsi rinonyanya kufarirwa ikozvino shandisa SMT tekinoroji, kune akawanda tafura paste bonding pad paPCB, iyo isina gomba welding. nzira, uye simbi mesh gomba inoenderana nepedhi yekubatanidza paPCB, bhuku rebhurashi mwero werata mubhurashi rakaomarara richava hafu yemvura uye yakasimba. mambure esimbi, uye ipapo zvikamu zvinonamirwaSMT muchina, uye ipapo zvikamu zvinoumbwa nereflow oven.
I. Kuvhura musimboti weSMT simbi mesh
1. CHIP mhando zvikamu katatu maererano nenzvimbo yose ye10 ~ 15[%], chengetedza chinhambwe chakafanana, uye wozogadzirisa maererano nezvinodiwa zvemutungamiri.
2. IC mhando yezvikamu (kusanganisira mutsara kuisa) kureba kune yakawedzera 0.1-0.20mm, hupamhi hwekutungamira zvinodiwa kugadzirisa, hunogona kukwidziridzwa zvakakodzera.
3. kupikisa uye kukwanisa mhando zvikamu, kureba kwekuwedzera 0.1mm.Upamhi hunogona kuchinjwa maererano nezvinodiwa nemutobvu
Zvimwe zvikamu zvinoramba zvakafanana nezvinodiwa pamusoro apa.
II.Kugamuchirwa kweSMT simbi mesh
1. simbi mesh tension 35≤F≤50 (N / cm) kukanganisa kukanganisa: F iri pasi kana yakaenzana ne8 (N / cm).
2. simbi mesh chitarisiko: mambure pamusoro pasina mavanga mavanga, hapana bump.
3. Pamberi pekugadzirwa kwesimbi itsva mesh, nyatsoisa mesh yesimbi pamushini wekudhinda, uye edza kudhinda 2 ~ 5 mahwendefa kuti usimbise kushandiswa kwekudhinda.
4. Mushure mokunge kugadzirwa kwekuedza kwapera, nyora nguva yekugadzira mumagwaro akakodzera ekugadzirisa grid grid.
III.Zvinodiwa pakudhinda fomati yeSMT simbi mesh
1. Kana imwe bhodhi uye imwe mambure, nzvimbo yegirafu yekuvhura inofanira kuiswa pakati.
2. Kana mapuranga maviri ePCB akasiyana akazarurwa mumambure esimbi akafanana, zvinodiwa kuti mativi emapuranga maviri aparadzaniswe ne30mm.
3. Kana maPCB maviri akafanana akavhurwa pamambure esimbi, nguva pakati pemahwendefa maviri e180 ° musangano inodiwa kuva 30mm.
