SMT Reflow Soldering yog dab tsi? email: susan@xmjuda.com
SMT Reflow Solderingyog cov txheej txheem tseem ceeb siv los solder Surface Mount Technology Cheebtsam mus rau Printed Circuit Board. (SMT yog luv rau nto mount technology).
Nws yog txoj kev sib koom ua ke tseem ceeb hauv kev tsim khoom siv hluav taws xob niaj hnub, lub luag haujlwm txuas rau feem ntau ntawm cov khoom (chips, resistors, capacitors, thiab lwm yam) koj pom ntawm cov laug cam hauv xov tooj, khoos phis tawj, thiab txhua yam khoom siv hluav taws xob.

Kauj Ruam 1: Solder Paste Printing
Lub stencil yog ua raws li PCB, thiab cov tshuaj txhuam hniav (ib qho sib xyaw ntawm cov pob me me thiab cov khoom siv hluav taws xob) tau luam tawm rau hauv cov ntaub ntawv tiag tiag uas cov khoom yuav zaum.
Kauj Ruam 2: Qhov Chaw Tso Npe
Kev xaiv-thiab- tso lub tshuab sai thiab raug tso cai SMT cov khoom rau ntawm cov khoom siv tshuaj txhuam hniav.
Kauj ruam 3: Reflow cua sov (Theem "Reflow")
Lub PCB sib sau ua ke taug kev los ntawm ntau -zone reflow qhov cub ntawm lub conveyor. Nws tau ua tib zoo tswj qhov kub thiab txias profile:
Preheat: Lub rooj tsavxwm maj mam ua kom sov kom qhib qhov flux.
Soak: Kub stabilizes, cia tag nrho cov board kom sov tusyees thiab flux los ntxuav cov hlau nto.
Reflow (Peak): Kub sai sai dhau los ntawm cov solder melting point (feem ntau yog 217℃+ rau txhuas-dawb). Cov tshuaj nplaum nplaum melts, ua kua, ntub cov khoom ua thiab PCB pads, thiab tsim ib daim ntawv cog lus metallurgical.
Txias: Lub rooj tsavxwm txias, tso cai rau cov pob qij txha kom khov thiab ua kom ruaj khov, txhim khu kev qha hluav taws xob thiab cov khoom siv sib txuas.
Kauj Ruam 4: Qhov tshwm sim
Cov zis yog ua tiav PCBA, npaj rau kev sim zaum kawg thiab kev koom ua ke rau hauv ib qho khoom.
Hom ntawm SMT Reflow Soldering Technology email: susan@xmjuda.com
Cov txheej txheem cua sov sib txawv yog siv rau kev siv sib txawv:
| Hom | Txoj Kev Kub Kub | Cov yam ntxwv tseem ceeb & zoo tshaj plaws rau |
|---|---|---|
| Convection Reflow | Circulated cua kub / nitrogen. | Feem ntau thiab raug nqi -txoj kev zoo. Zoo tagnrho rau siab - ntim khoom siv hluav taws xob. |
| Vapor Phase Reflow | Latent cua sov los ntawm condensing inert vapor (xws li, PFPE kua). | Qhov kub thiab txias tsis sib xws thiab xoom- oxygen ib puag ncig. Siv rau siab -kev cia siab, siab- ceev, los yog cua sov- cov rooj sib txoos rhiab heev (xws li, aerospace, automotive, advanced ntim). |
| Infrared Reflow | Infrared hluav taws xob. | Cov cua kub ceev, tab sis tsis sib xws. Feem ntau ua ke nrog convection hauv qhov cub niaj hnub. |
| Laser Reflow | Focused laser beam. | Ultra-paj meej, cov cua sov hauv zos. Siv rau micro- vuam, kho, lossis cov khoom sib txawv tshwj xeeb. |
Peb cov khoom PFPE kua JHLS series yog cov kua dej ua haujlwm tseem ceeb rau Vapor Phase Reflow, ua rau nws qhov kev ua haujlwm tsis sib haum xeeb rau siab - kev ntseeg siab, siab - ntom ntom, los yog cua sov- cov khoom sib dhos yooj yim (xws li aerospace, automotive, advanced ntim).
PFPE kua JHLS series tsis yog cov kua dej tsis zoo xwb; nws yog cov khoom siv hauv paus uas ua rau cov txheej txheem zoo tshaj no ua tau. Nws cov khoom tsim kho vaj tse muab cov kev pabcuam dav dav:
Unrivaled Chemical thiab Thermal Stability:JHLS PFPE tseem inert thiab ruaj khov ntawm qhov kub thiab txias tsis tu ncua. Nws tsis decompose los tsim cov kua qaub los yog sludge, ua kom lub neej ntev ntawm cov kua dej thiab tiv thaiv cov khoom rhiab thiab cov pob qij txha los ntawm cov tshuaj tua kab mob.
Engineered Boiling Point rau Precision:Muaj nyob rau hauv cov qib tshwj xeeb, JHLS PFPE tso cai rau cov tuam txhab xaiv qhov tseeb, ruaj khov taw tes kom haum rau lawv cov hlau lead-dawb solder profile, lav cov txheej txheem rov ua dua.
Superior Yield thiab Reliability:Los ntawm kev ua kom muaj kev sib haum xeeb zoo tshaj plaws thiab cov pa oxygen- ib puag ncig pub dawb, JHLS PFPE ncaj qha tackles lub hauv paus ua rau muaj kev cuam tshuam ntawm kev sib txuas ua ke -bridging, tombstoning, thiab txias pob qij txha- tsav tsheb ua ntej - dhau tawm los thiab ntev - cov khoom lag luam ntseeg siab rau qhov siab tshiab.
Tag Nrho Tus Nqi Ntawm Cov Tswv Cuab Tau Zoo:Qhov txo qis hauv cov pa roj nitrogen, hluav taws xob hluav taws xob, kev tsim khoom poob qis rau kev tu, thiab kev sib koom ua haujlwm sib koom ua ke muab ROI tsim nyog, ua rau nws yog qhov kev xaiv zoo rau kev tsim khoom muaj txiaj ntsig siab.
