1. PCB hapana muitiro mupendero, maburi maburi, haigoni kusangana SMT midziyo clamping zvinodiwa, izvo zvinoreva kuti haigoni kuzadzisa zvinodiwa uwandu kugadzirwa.
2. PCB chimiro mutorwa kana saizi yakakura kwazvo, idiki, yakafanana haigone kusangana nezvinodiwa zvemidziyo clamping.
3. PCB, FQFP Mapedhi kumativi hapana optical Positioning chiratidzo (Mako) kana Mark pfungwa haisi mwero, akadai Mark pfungwa kumativi solder kuramba firimu, kana yakakura kwazvo, diki, zvichiguma Mark pfungwa mufananidzo musiyano idiki, muchina. kazhinji alarm haigone kushanda nemazvo.
4. Saizi yekugadzira padhi haina kurongeka, senge pad spacing yezvikamu zvechip yakakura kwazvo, idiki, iyo padhi haina symmetrical, zvichikonzera kukanganisa kwakasiyana-siyana mushure mekusungirirwa kwezvinhu zvechip, senge skewed, yakamira monument. .
5. Mapedhi ane-over-gole achaita kuti solder inyunguduke nepaburi kusvika pasi, zvichiita kuti solder shoma shoma.
6. Chip components pad size haina symmetrical, kunyanya neland line, pamusoro pemutsara wechikamu chekushandiswa sepadhi, kuitira kuti.reflow ovensoldering chip components kumativi ose maviri epadhi isina kuenzana kupisa, solder paste yakanyunguduka uye yakakonzerwa nekuremara kwechiyeuchidzo.
7. IC padhi dhizaini haina kururama, FQFP mupedhi yakawandisa, zvichiita kuti bhiriji mushure mekugadzira kunyange, kana padhi mushure memucheto ipfupi inokonzerwa nekusakwana kwesimba mushure mekuputika.
8. IC mapedhi pakati pematambo ekubatanidza akaiswa pakati, asingakodzeri kune SMA post-soldering inspection.
9. Wave soldering muchinaIC hapana dhizaini yekubatsira pads, zvichikonzera post-soldering bhiriji.
10. PCB ukobvu kana PCB muI IC kugovera haina musoro, iyo PCB deformation mushure mekunama.
11. Chiyero chekuyera dhizaini hachina kumira, kuitira kuti ICT isashande.
12. Mukaha pakati peSMD hauna kururama, uye matambudziko anomuka mukugadzirisa gare gare.
.
14. dhizaini isinganzwisisike ye splicing board, senge kusashanda zvakanaka kweV-slots, zvichikonzera PCB deformation mushure mekuyerera.
Izvo zvikanganiso zviri pamusoro zvinogona kuitika mune imwe kana kupfuura yezvigadzirwa zvisina kugadzirwa zvakanaka, zvichikonzera kusiyana kwakasiyana-siyana pamhando ye soldering.Vagadziri havazivi zvakakwana nezveSMT maitiro, kunyanya zvikamu mu reflow soldering ine "simba" maitiro haanzwisisi chimwe chezvikonzero zvekugadzirwa kwakashata.Pamusoro pezvo, dhizaini yakambofuratira maitiro evashandi kuti vatore chikamu mukushaikwa kweiyo bhizinesi dhizaini magadzirirwo ekugadzirwa, ndicho chikonzero chekugadzira kwakashata.
