Fine Pitch SMT yog dab tsi?
Fine Pitch SMT yog hais txog cov txheej txheem ntawm siab - qhov ntom ntom ntawm cov khoom siv hauv PCBs, feem ntau yog rau cov khoom siv nrog tus pin suab ntawm 0.5 hli lossis tsawg dua (xws li QFP, BGA, thiab CSP).
Cov yam ntxwv muaj xws li
- High - cov txheej txheem ntom ntom, nrog cov khoom sib xyaw ua ke ib square inch ntau dua li cov rooj sib tham.
- Cov pob khoom siv: 0201, 0402, 0603, thiab lwm yam micro-SMDs.
- Cov kev xav tau siab heev rau kev tso kawm raug, soldering zoo, thiab kev tshuaj xyuas txoj kev.
Common Fine Pitch Component Hom
- QFP (Quad Flat Package)
- BGA (Ball Grid Array)
- CSP (Chip Size Pob)
- Micro-SMDs (0201, 0402, 0603, thiab lwm yam)
Cov khoom no muaj cov pin pitches me me thiab txwv qhov ntau thiab tsawg, tso cov kev xav tau nruj me ntsis ntawm cov ntawv luam tawm, qhov tseeb qhov chaw, thiab kev tswj xyuas qhov profile.
Lub luag haujlwm tseem ceeb ntawm Stencils thiab Solder Paste Printing
Stencil Khoom
Laser{0}} txiav stainless hlau nrog siab aperture precision.
Aperture Tsim
Optimized zoo thiab loj raws li pad geometry kom ntseeg tau tias du solder paste tso tawm.
Thickness Tswj
Feem ntau nyob ib ncig ntawm 0.10 mm - tuab heev tuaj yeem ua rau kev sib txuas, nyias nyias tuaj yeem ua rau cov pob qij txha tsis txaus.
Cov ntsiab lus tseem ceeb rau Fine Pitch PCB Tsim
- Kev xaiv cov khoom siv: Ua ntej cov pob khoom tsim nyog rau siab - layouts ceev.
- Rating Margin: Tso cai rau 20-30% margin rau cov khoom xws li capacitors thiab resistors.
- Board Loj thiab Layout: Txo qhov loj ntawm lub rooj tsavxwm yog qhov ua tau, ua qhov tseem ceeb ntawm - nrawm / siab- cov khoom siv fais fab.
- Qhov chaw thiab Routing: Precision tso tshuab yog qhov tseem ceeb; BGAs yuav tsum tau kuaj X-ray.
Txheej txheem Optimization thiab tshuaj xyuas
- Ntawm -hauv-Pad: Txuag routing qhov chaw thiab tiv thaiv kev sib tsoo.
- Fiducial Marks: Muab kev pom kev sib haum xeeb rau cov tshuab tso.
- Decoupling Capacitor Placement: Txoj hauj lwm ze rau lub hwj chim pins.
- Txoj Kev Tshuaj Xyuas: AOI, X-ray, thiab kev kuaj ua haujlwm tag nrho.
- Kev Tiv Thaiv Reflow: Nitrogen cua txo cov kev pheej hmoo oxidation.
Cov kev sib tw thiab cov kev ntsuas
- Solder Paste Printing nyuaj → Precision stencil + tswj txheej txheem luam ntawv nruj.
- High Placement Accuracy Requirements → High -Qhov chaw muab qhov tseeb + AOI tshuaj xyuas.
- Kev pheej hmoo siab ntawm Soldering Defects → Optimized reflow profile + X-ray tshuaj xyuas.
- Rework nyuaj → Kub-tswj rework chaw nres tsheb + microscopic ua haujlwm.
