1. Txo qhov kub ntawmreflow qhov cublos yog kho tus nqi cua sov thiab txias ntawm lub phaj thaum lub sij hawmreflow soldering tshuabtxo qhov tshwm sim ntawm phaj dabtsi yog khoov thiab warping;
2. Lub phaj nrog TG siab dua tuaj yeem tiv taus qhov kub thiab txias, ua kom muaj peev xwm tiv taus siab deformation los ntawm qhov kub thiab txias, thiab hais lus, cov khoom siv yuav nce;
3. Ua kom lub thickness ntawm lub rooj tsavxwm, qhov no tsuas yog siv tau rau cov khoom nws tus kheej tsis xav tau cov thickness ntawm cov khoom PCB, cov khoom siv hnyav tsuas yog siv lwm txoj hauv kev;
4. Txo tus naj npawb ntawm cov laug cam thiab txo qhov loj ntawm lub rooj tsav xwm hauv Circuit Court, vim tias lub rooj tsavxwm loj dua, qhov loj dua, lub rooj tsav tsheb hauv lub zos rov qab tom qab qhov kub thiab txias, lub zog hauv zos sib txawv, cuam tshuam los ntawm nws tus kheej qhov hnyav, yooj yim. ua rau lub zos kev nyuaj siab deformation nyob rau hauv nruab nrab;
5. Lub phaj fixture yog siv los txo qhov deformation ntawm Circuit Court board.Lub Circuit Court board yog txias thiab shrunk tom qab kub thermal expansion los ntawm reflow vuam.Lub phaj fixture tuaj yeem ua kom ruaj khov ntawm lub rooj tsavxwm, tab sis cov khoom siv lim phaj yog kim dua, thiab nws yuav tsum tau nce phau ntawv tso rau ntawm lub tais ntim khoom.
