Kodi Njira Yoyesera ya SMT ndi Chiyani?

Makina a SMT AOI

Pakuwunika kwa SMT, kuyang'ana kowoneka ndi kuyang'anira zida zamagetsi zimagwiritsidwa ntchito nthawi zambiri.Njira zina zimangoyang'ana m'maso, ndipo zina zimakhala zosakanikirana.Onsewa akhoza kuyang'ana 100% ya mankhwala, koma ngati njira yowunikira maso ikugwiritsidwa ntchito, anthu amakhala otopa nthawi zonse, choncho sizingatheke kuonetsetsa kuti ogwira ntchito akuwunika mosamala 100%.Choncho, timakhazikitsa ndondomeko yoyenera yowunikira ndi kuyang'anira pokhazikitsa malo oyendetsera ntchito.

Pofuna kuonetsetsa kuti zipangizo za SMT zikugwira ntchito bwino, limbitsani kuyang'anitsitsa kwabwino kwa makina opangira makina mu ndondomeko iliyonse, kuti ayang'ane momwe akugwirira ntchito, ndikukhazikitsa mfundo zoyendetsera khalidwe pambuyo pa njira zina zofunika.
Malo owongolera awa nthawi zambiri amakhala m'malo otsatirawa:

1. Kuwunika kwa PCB
(1) Palibe kusinthika kwa bolodi losindikizidwa;
(2) Kaya pad kuwotcherera ndi oxidized;
(3) Palibe zokanda pamwamba pa bolodi losindikizidwa;
Njira yoyendera: Kuyang'ana kowoneka molingana ndi muyezo woyendera.

2. Screen yosindikiza kuzindikira
(1) Kaya kusindikiza kwatha;
(2) Kaya pali mlatho;
(3) Kaya makulidwewo ndi ofanana;
(4) Palibe kugwa kwa m'mphepete;
(5) Palibe kupatuka pakusindikiza;
Njira yoyendera: kuyang'ana kowoneka kapena kuyang'anira magalasi mokulira molingana ndi muyezo woyendera.

3. Kuyesa kwa zigamba
(1) Malo okwera a zigawo;
(2) Kaya pali dontho;
(3) Palibe mbali zolakwika;
Njira yoyendera: kuyang'ana kowoneka kapena kuyang'anira magalasi mokulira molingana ndi muyezo woyendera.

4. Reflow uvunikuzindikira
(1) The kuwotcherera mkhalidwe wa zigawo zikuluzikulu, kaya pali mlatho, mwala, dislocation, mpira solder, kuwotcherera pafupifupi ndi zochitika zina zoipa kuwotcherera.
(2) Mkhalidwe wa solder joint.
Njira yoyendera: kuyang'ana kowoneka kapena kuyang'anira magalasi mokulira molingana ndi muyezo woyendera.
