Monga gawo lofunikira pazida zonse zamagetsi, ukadaulo wodziwika kwambiri padziko lonse lapansi umafunikira wathunthu PCB kupanga. Komabe, ndondomeko yokha nthawi zina ilibe kanthu. Zosakhwima komanso zovuta, zolakwika zimachitika nthawi zambiri pamapangidwe a PCB. Chifukwa cha kuchedwa kupanga chifukwa cha reflow board board, zotsatirazi ndi zolakwika zitatu za PCB zomwe ziyenera kudziwidwa kuti tipewe zolakwika.

1.) Njira yolowera

Ngakhale mapulogalamu ambiri a PCB amaphatikizapo malaibulale a General Electric, zizindikiro zawo zofananira ndi momwe amatera, ma board ena ozungulira amafunikira opanga kuti ajambule pamanja. Ngati cholakwikacho ndi chochepera theka la millimeter, injiniya ayenera kukhala wokhwima kwambiri kuti awonetsetse kuti pali kusiyana koyenera pakati pa mapepala. Zolakwa zomwe zimachitika panthawi yopangira izi zimapangitsa kuwotcherera kukhala kovuta kapena kosatheka. Kukonzanso koyenera kungayambitse kuchedwa kokwera mtengo.

2.) Gwiritsani ntchito njira zakhungu/zokwiriridwa

Pamsika wa zida zomwe zidazolowera kugwiritsa ntchito IoT masiku ano, zinthu zing’onozing’ono ndi zazing’ono zikupitilizabe kukhudza kwambiri. Pamene zipangizo ang’onoang’ono amafuna PCBs ang’onoang’ono, akatswiri ambiri amasankha kugwiritsa ntchito vias akhungu ndi vias m’manda kuchepetsa mapazi a bolodi dera kulumikiza zigawo mkati ndi kunja. Ngakhale kudutsa dzenje kumatha kuchepetsa dera la PCB, kumachepetsa malo opangira ma waya, ndipo kuchuluka kwa zowonjezera kumawonjezeka, kumatha kukhala kovuta, zomwe zimapangitsa matabwa ena kukhala okwera mtengo komanso osatheka kupanga.

3.) Tsatani m’lifupi

Pofuna kupanga kukula kwa bolodi kukhala kakang’ono komanso kophatikizana, cholinga cha injiniya ndikupangitsa kuti mayendedwewo akhale opapatiza momwe angathere. Kuzindikira PCB kufufuza m’lifupi kumaphatikizapo zosintha zambiri, zomwe zimapangitsa kuti zikhale zovuta, kotero ndikofunikira kumvetsetsa kuti ndi ma milliamp angati omwe adzafunikire. Nthawi zambiri, kufunikira kocheperako sikukwanira. Tikukulimbikitsani kugwiritsa ntchito chowerengera cham’lifupi kuti muwone makulidwe oyenera ndikuwonetsetsa kulondola kwa mapangidwe.
