Qalabka Alaabta
Sida alaab-qeybiyaha teknoolajiyada kala duwan ee PCB, mugga, fursadaha wakhtiga hogaanka, waxaanu leenahay xulashada agabka caadiga ah kaas oo baaxad weyn oo noocyada kala duwan ee PCB ah lagu dabooli karo oo had iyo jeer laga helo guriga.
Shuruudaha agabka kale ama khaaska ah sidoo kale waa la buuxin karaa xaaladaha badankood, laakiin, iyadoo ku xiran shuruudaha saxda ah, ilaa 10 maalmood oo shaqo ayaa loo baahan karaa si loo soo iibiyo alaabta.
Nala soo xidhiidh oo kala hadal baahiyahaaga mid ka mid ah iibkayaga ama kooxda CAM.

Q&A Sida Loo Tijaabsado Xoojinta Darbiga Daloolka Iyo Tilmaamaha La Xidhiidha
Sidee loo tijaabiyaa xajinta gidaarka daloolka iyo waxyaabaha la xidhiidha?Darbiga daloolka ayaa ka saaraya sababaha iyo xalalka?
Tijaabada jiidista gidaarka ayaa hore loogu dabaqay qaybaha daloolka si loo buuxiyo shuruudaha isu-ururinta.Tijaabada guud waa in lagu iibiyo siliga looxa pcb godadka ka dibna lagu cabbiro qiimaha soo jiidashada mitirka xiisadda.Sida laga soo xigtay waayo-aragnimada, qiyamka guud waa mid aad u sarreeya, taas oo ka dhigaysa ku dhawaad wax dhibaato ah codsiga.Tilmaamaha alaabadu way kala duwan yihiin
Shuruudaha kala duwan, waxaa lagu talinayaa in la tixraaco qeexitaannada IPC ee la xiriira.
Dhibaatada kala soocida derbiga daloolka waa arrinta ku dheggan liidata, taas oo guud ahaan ay sababto laba sababood oo caadi ah, midda koowaad waa xajinta desmear liidata (Desmear) waxay ka dhigaysaa xiisadda mid aan ku filnayn.Midda kale waa habka dahaarka naxaasta electroless ama si toos ah dahab dahaadhay, Tusaale ahaan: koritaanka qaro weyn, raso weyn waxay keeni doontaa in adhesion liidata.Dabcan waxaa jira arrimo kale oo suurtagal ah oo saameyn kara dhibaatadan, si kastaba ha ahaatee labadan arrimood ayaa ah dhibaatooyinka ugu caansan.
Waxaa jira laba faa'iido darrooyinka derbiga godka, midka ugu horreeya ee koorsada waa jawi shaqo oo tijaabo ah oo aad u adag ama adag, waxay keeni doontaa in guddiga pcb uusan u adkeysan karin walbahaarka jirka si ay u kala soocaan.Haddii dhibaatadan ay adag tahay in la xalliyo, waxaa laga yaabaa inaad bedesho alaabta laminate si aad u hagaajiso.
Haddii aysan ahayn dhibaatada kor ku xusan, waxay inta badan sabab u tahay ku-xidhka liita ee u dhexeeya naxaasta daloolka iyo derbiga daloolka.Sababaha suurtogalka ah ee qaybtan waxaa ka mid ah qallafsanaan ku filan derbiga daloolka, dhumucda xad-dhaafka ah ee naxaasta kiimikada, iyo cilladaha is-dhexgalka ee ay sababto daaweynta habka naxaasta kiimikada liidata.Kuwaas oo dhan waa sabab macquul ah.Dabcan, haddii tayada qodista ay liidato, kala duwanaanshaha qaabka gidaarka daloolka ayaa sidoo kale sababi kara dhibaatooyinkaas.Marka laga hadlayo shaqada aasaasiga ah ee lagu xallinayo dhibaatooyinkan, waa in marka hore la xaqiijiyo sababta asalka u ah ka dibna wax laga qabto isha sababta ka hor inta aan si dhammaystiran loo xallin.
