Sida Looga Hortago PCB Board-ka Inay Laabtaan Oo Ay Diriraan Marka La Marayo Foornada Dib U Qulqulaya

Sida aan wada ognahay, PCB waxay u nugul tahay foorarsiga iyo gariirinta marka ay dhex mareyso foornada dib u soo qulqulaya.Sida looga hortago PCB inay foorarsato oo gariirto marka la marayo foornada dib-u-qulqulaya ayaa lagu sharaxay hoos

1. Iska yaree saamaynta heerkulka ku leeyahay walbahaarka PCB

Maadaama "heerkulka" uu yahay isha ugu weyn ee cadaadiska saxanka, ilaa inta heerkulka foornada dib-u-soo-celinta la yareeyo ama heerkulka kuleylka iyo qaboojinta ee foornada dib u soo celinta ay hoos u dhacdo, dhacdada foorarsiga saxanka iyo qulqulka si weyn ayaa loo yareyn karaa.Si kastaba ha ahaatee, waxaa jiri kara waxyeelo kale, sida alxanka wareegga gaaban.

2. Qaado saxanka sare ee TG

TG waa heerkulka kala-guurka dhalada, taas oo ah, heerkulka maaddadu ay ka beddesho xaaladda dhalada ilaa gobolka rubberized.Qiimaha hoose ee TG ee maaddada, sida ugu dhakhsaha badan saxanku wuxuu bilaabaa inuu jilciyo ka dib marka la galo foornada dib-u-soo-celinta, iyo muddada dheer ee lagu noqonayo gobolka jilicsan ee jilicsan, ayaa ka sii daran cilladda saxanka.Awoodda culeyska culeyska iyo qallafsanaanta waxaa lagu kordhin karaa iyadoo la adeegsanayo saxanka leh TG sare, laakiin qiimaha alaabtu waa mid aad u sarreeya.

3. Kordhi dhumucda looxa wareegga

Alaabooyin badan oo elektiroonig ah si loo gaaro ujeedada khafiifka ah, dhumucda guddiga ayaa laga tagay 1.0 mm, 0.8 mm, ama xitaa 0.6 mm, dhumucdiisuna waxay tahay in lagu ilaaliyo guddiga ka dib foornada dib-u-soo-celinta ma qallajiso, runtii waa xoogaa yar. adag, waxaa la soo jeediyay in haddii aysan jirin shuruudo khafiif ah, guddiga isticmaali kartaa dhumucdiisuna 1.6 mm, taas oo si weyn u yaraynaysaa halista ah ee foorarsiga iyo qalloocin.

4. Iska yaree cabbirka sabuuradda wareegga iyo tirada dabaylaha

Maadaama foornooyinka dib-u-qulqulaya intooda badani isticmaalaan silsilado si ay horay ugu sii wadaan looxyada wareegga, xajmiga weyn ee guddiga wareegga, inta badan waxay ku jiri doontaa foornada dib-u-soo-celinta culeyskeeda awgeed.Sidaa darteed, haddii dhinaca dheer ee looxa wareegga lagu dhejiyo silsiladda foornada dib-u-soo-celinta sida cidhifka looxa, cilladda qallafsan ee ay keento miisaanka wareegga wareegga waa la dhimi karaa, tirada looxyada waa la dhimi karaa sababtan, Taasi waa in la yidhaahdo, marka foornada, isku dayaan in ay isticmaalaan dhinaca cidhiidhi ah si toos ah jihada foornada, gaari karaa in deformation sag hoose.

5. Isticmaalay qalabka palette-ka

Haddii dhammaan hababka kor ku xusan ay adag tahay in la gaaro, Waa in la isticmaalo side reflow / template si loo yareeyo deformation.Sababta dib-u-qulqulaya side / template waxay yarayn kartaa foorarsiga iyo qulqulka guddiga waa iyada oo aan loo eegin haddii ay tahay balaadhinta kulaylka ama foosha qabow, saxaarad ayaa la filayaa inay qabato guddiga wareegga.Marka heerkulka guddiga wareegga uu ka hooseeyo qiimaha TG oo uu bilaabo inuu sii adkeeyo mar kale, waxay ilaalin kartaa cabbirka wareega.

Haddii saxaarad hal-lakab ah aysan hoos u dhigi karin qallafsanaanta guddiga wareegga, waa in aan ku darnaa lakabka daboolka si loo xiro guddiga wareegga laba lakab oo saxan ah, taas oo si weyn u yareyn karta qallafsanaanta guddiga wareegga iyada oo loo marayo foornada dib u soo celinta.Si kastaba ha ahaatee, saxaarada foornada waa mid aad qaali u ah, waxayna sidoo kale u baahan tahay in lagu daro buug-gacmeed si loo dhigo oo dib loo warshadeeyo saxarada.

6. Isticmaal router halkii aad ka isticmaali lahayd V-CUT

Maadaama V-CUT ay dhaawici doonto xoogga qaabdhismeedka looxyada wareegyada, isku day inaadan isticmaalin kala qaybsanaanta V-CUT ama hoos u dhigto qoto dheer ee V-CUT.
