1. Raws li cov kev cai ntawm GJB3835, tom qab warping thiab deformation vuam ntawm PCBA hauvreflow qhov cubwelding txheej txheem, qhov siab tshaj plaws warping thiab distortion yuav tsum tsis txhob ntau tshaj 0.75%, thiab warping thiab distortion ntawm PCB nrog nplua-spacing Cheebtsam yuav tsum tsis txhob ntau tshaj 0.5%.
2. PCBA nrog pom tseeb warping, yog hais tias lub multi-layer PCBA muaj deformation kev nyuaj siab, nrog rau kev txhim kho ntawm hlau ncej installation, chassis platform ntsia hlau installation, chassis qhia rail qhia groove insertion thiab lwm yam thim rov qab deformation installation (insertion), nws yuav ua rau kev puas tsuaj los yog tawg rau lub metallization qhov ntawm cov xov hlau luam tawm xws li high-density IC thiab lwm yam khoom siv, BGA / CCGA solder pob qij txha thiab relay qhov ntawm multilayer PCB.
3. PCBA nrog distortion los yog bowing mus txog 0.75% yuav tsum tau ntsia raws li cov kev cai nram qab no yog tias nws tau lees paub tias qhov deformation kev nyuaj siab tsis ua rau cov khoom puas tsuaj thiab kev ntseeg siab thiab nws yuav tsum tau siv txuas ntxiv mus.
Nruab (ntxig) thiab ntsia hlau fastening ncaj qha rau ntawm lub chassis platform, qhia groove, qhia kev tsheb nqaj hlau lossis ncej yuav tsum tsis txhob ua kom tsis txhob muaj kev puas tsuaj ntxiv rau cov khoom thiab cov qhov metallized los ntawm qhov rov qab deformation kev nyuaj siab ntawm PCB los ua ke.
Kev ntsuas lub txaj hauv zos (cov khoom siv hluav taws xob lossis cov khoom siv thermal conductive) yuav tsum tau coj mus rau qhov chaw uas qhov sib txawv thiab khoov deformation qhov sib txawv yog qhov loj tshaj plaws, tsis muaj kev cuam tshuam rau kev txhim kho kev ntseeg siab thiab ua kom lub ntsiab thermal lossis conductive raws.Lub warping ib feem tuaj yeem ntsia tau thiab fastened tsuas yog nyob rau hauv cov xwm txheej uas deformed luam tawm Circuit Board sib dhos tsis dais qhov rov qab deformation kev ntxhov siab.
4. Lub rigidity thiab deformation muaj peev xwm ntawm cov ntaub ntawv uas tau xaiv rau lub PCB installation qauv thiab reinforcement ncej yuav tsum tsis txhob ua distortion los yog bow deformation los yog rov qab deformation ntawm PCB.
5. Rau lub multilayer PCBA nrog pom tseeb distortion los yog bowing, los yog distortion ( bowing) tsawg tshaj li 0.75%, tshwj xeeb tshaj yog cov PCBA nruab nrog high-density IC, BGA / CCGA Cheebtsam, kho los yog anti-deformation installation ntawm PCB yuav tsum nruj me ntsis txwv tsis pub. .
