Ulwazi lwe-SMT Steel Mesh

Iphrinta ye-NeoDen Stencil YS350

I-SMT steel mesh isetshenziselwa isimo esiwuketshezi nesiqinile sokuphrinta unamathisele we-solder ebhodini le-PCB, ibhodi lesifunda ngaphezu kwebhodi lamandla ethandwa kakhulu manje lisebenzisa ubuchwepheshe be-SMT, maningi amathebula okunamathisela okunamathisela okunamathisela okunamathiselwe kwi-PCB, okungukuthi ngaphandle kokushisela imbobo. indlela, futhi imbobo yensimbi yensimbi ihambisana nephedi yokubopha ku-PCB, ibhulashi lezandla izinga lethini kubhulashi eliqinile lizoba uhhafu woketshezi futhi liqine. inetha lensimbi, bese izingxenye zinamathiselweUmshini we-SMT, bese izingxenye zakhiwe ngureflow oven.

I. Umgomo wokuvula we-SMT steel mesh
1. Izingxenye zohlobo lwe-CHIP izikhathi ezintathu ngokuya ngendawo ephelele engu-10~15[%], gcina ibanga elifanayo, bese ulungisa ngokuvumelana nezidingo zomthofu.
2. Izingxenye zohlobo lwe-IC (okuhlanganisa nokufakwa komugqa) ubude ukuya kowengeziwe ongu-0.1-0.20mm, ububanzi bezidingo zomthofu okufanele zilungiswe, zinganwetshwa ngokufanelekile
3. ukumelana nezingxenye zohlobo lomthamo, ubude be-0.1mm eyengeziwe.Ububanzi bungashintshwa ngokuya ngesidingo somthofu
Ezinye izingxenye zihlala zifana nezimfuneko ezingenhla.

II.Ukwamukelwa kwe-SMT steel mesh
1. I-steel mesh tension 35≤F≤50 (N/cm) iphutha le-tension: F ingaphansi noma ilingana no-8 (N/cm).
2. ukubukeka kwensimbi yensimbi: indawo enetha engenazimpawu zokuklwebheka, akukho qhubu.
3. Ngaphambi kokukhiqizwa kwensimbi entsha yensimbi, faka kahle insimbi yensimbi emshinini wokunyathelisa, bese uzama ukuphrinta amapuleti angu-2 ~ 5 ukuze uqinisekise umphumela wokuphrinta.
4. Ngemuva kokuthi ukukhiqizwa kwesilingo sekudlulisiwe, bhala isikhathi sokukhiqiza kumadokhumenti afanelekile wokuphathwa kwegridi yensimbi.

III.Izidingo zefomethi yokuphrinta ye-SMT steel mesh
1. Lapho ibhodi elilodwa nenetha eyodwa, indawo yegrafu yokuvula kufanele igxile.
2. Lapho amabhodi amabili e-PCB ahlukene evulwa enetheni elilodwa lensimbi, kudingeka ukuthi imiphetho yamabhodi amabili ihlukaniswe ngo-30mm.
3. Uma i-PCB emibili efanayo ivulwa enethini yensimbi, isikhawu phakathi kwamapuleti amabili okuhlanganiswa okungu-180° sidingeka sibe ngu-30mm.
