Nyob rau hauv lub tshav pob ntawm precision ua khoom, qhov zoo ntawm laser bonding ntawm granite bases ncaj qha cuam tshuam rau stability ntawm cov khoom. Txawm li cas los xij, ntau lub lag luam tau poob rau hauv qhov teeb meem ntawm kev poob qis thiab kev saib xyuas tsis tu ncua vim tsis saib xyuas cov ntsiab lus tseem ceeb. Kab lus no tau nthuav tawm cov kev pheej hmoo zoo los pab koj kom tsis txhob muaj kev pheej hmoo zais thiab txhim kho kev tsim khoom.
I. Bonding txheej txheem tsis xws luag: "Hidden Mode" ntawm Precision Killer
Tsis sib npaug thickness ntawm cov nplaum txheej ua rau lub deformation yuav tsis tswj
Cov txheej txheem tsis yog txheej txheem laser sib txuas yog qhov ua rau muaj qhov sib txawv ntawm cov nplaum txheej tuab tshaj ± 0.1mm. Hauv kev sim thermal cycling, qhov sib txawv ntawm qhov nthuav coefficient ntawm cov nplaum txheej thiab granite (txog 20 × 10⁻⁶ / ℃ rau cov nplaum txheej thiab tsuas yog 5 × 10⁻⁶ / ℃ rau granite) yuav ua rau cov kab deformation ntawm 0.01mm / m. Vim yog cov nplaum nplaum tuab heev, Z-axis qhov yuam kev ntawm qee yam khoom siv kho qhov muag tsis zoo los ntawm ± 2μm mus rau ± 8μm tom qab cov khoom siv tau ua haujlwm rau 3 lub hlis.
2. Kev ntxhov siab concentration ua rau lub cev tsis ua haujlwm
Kev sib raug zoo tsis zoo ua rau muaj kev sib txawv tsis sib xws, ua rau muaj kev ntxhov siab hauv zos ntau dua 30MPa ntawm ntug ntawm lub hauv paus. Thaum cov cuab yeej vibrates ntawm kev kub ceev, microcracks nquag tshwm sim hauv cheeb tsam kev ntxhov siab. Ib rooj plaub ntawm lub tsheb pwm ua chaw ua haujlwm qhia tau hais tias cov txheej txheem kev sib txuas ua haujlwm tsis zoo ua rau lub neej ua haujlwm ntawm lub hauv paus los ntawm 40% thiab tus nqi txij nkawm nce 65%.
Ii. Cov Khoom Siv Sib Tw: Qhov Kev Pom Zoo "Fatal Weakness"
Resonance yog tshwm sim los ntawm qhov ntom ntawm granite tsis ua raws li tus qauv
Kev ua haujlwm tsis zoo ntawm cov granite tsis zoo (qhov ntom <2600kg / m³) tau txo qis los ntawm 30%, thiab nws tsis tuaj yeem nqus tau lub zog zoo nyob rau hauv high-frequency vibration (20-50Hz) thaum lub sij hawm laser ua. Ib qho PCB lub Hoobkas qhov kev sim tiag tiag qhia tau hais tias thaum siv lub hauv paus tsis tshua muaj zog granite, qhov chipped ntug tus nqi thaum lub sij hawm drilling yog siab li 12%, thaum cov ntaub ntawv zoo tsuas yog 2%.
2. Cov nplaum nplaum muaj qhov kub tsis txaus
Ordinary adhesives tuaj yeem tiv taus kub hauv qab 80 ℃. Nyob rau hauv qhov kub-kub ib puag ncig ntawm laser ua (hauv zos tshaj 150 ℃), cov nplaum txheej softens, ua rau lub hauv paus qauv loosen. Ib qho kev lag luam semiconductor ua rau muaj kev puas tsuaj rau lub taub hau laser muaj nqis lab vim qhov tsis ua haujlwm ntawm cov nplaum.
Iii. Risk of Missing Certifications: Tus nqi zais ntawm "Peb-tsis khoom"
Lub hauv paus tsis muaj ntawv pov thawj CE thiab ISO zais qhov muaj peev xwm muaj kev nyab xeeb:
Kev siv hluav taws xob ntau dhau: Granite tsis tuaj yeem tso tawm cov roj radon, ua rau muaj kev hem thawj rau kev noj qab haus huv ntawm cov neeg ua haujlwm.
Kev kos cim tsis raug ntawm lub peev xwm thauj khoom: qhov tseeb ntawm cov kabmob muaj peev xwm tsawg dua 60% ntawm tus nqi cim, ua rau muaj kev pheej hmoo ntawm cov khoom siv rov qab.
Kev tiv thaiv ib puag ncig tsis ua raws: VOCS-muaj cov nplaum nplaum ua rau lub chaw ua haujlwm ib puag ncig thiab tab tom ntsib kev tiv thaiv ib puag ncig.
Iv. Phau Ntawv Qhia Kom Zam Kev Tsis Txaus Siab: Qhov "Golden Rule" ntawm Kev Tswj Xyuas Zoo
✅ Ob chav tshuaj xyuas: Granite ntom (≥2800kg / m³) thiab yuav tsum tau kuaj cov xov tooj cua;
✅ Cov txheej txheem pom: Xaiv cov chaw muag khoom siv laser interferometer los saib xyuas cov nplaum tuab (yuam kev ≤ ± 0.02mm);
✅ Simulation xeem: ** thermal cycling (-20 ° C txog 80 ° C) + vibration (5-50Hz) ** ob chav xeem cov ntaub ntawv yuav tsum tau;
✅ Daim ntawv pov thawj tiav: Paub meej tias cov khoom muaj CE, ISO 9001 thiab ib puag ncig SGS ntawv pov thawj.
