PCB Pad ka saaray Saddexda Sababood ee Caadiga ah

Habka isticmaalka guddiga PCBA, inta badan waxaa jiri doona ifafaale of pad off, gaar ahaan waqtiga hagaajinta guddiga PCBA, marka la isticmaalayo birta alxanka ah, aad bay u fududahay in line pad off ifafaale, PCB warshad waa in ay ahaataa sida wax looga qabto?Warqadan, sababaha suufka ayaa ka saaray falanqaynta qaarkood.

1. Dhibaatooyinka tayada saxanka

Sababo la xiriira bireed naxaas ah saxan naxaas-xidhan iyo xabagta epoxy dhexeeya adhesion xabagta xabagta xabagta waa xad liidata, in uu yahay, xitaa haddii aag weyn oo bireed naxaas guddiga wareegga bireed naxaas wax yar kululeeyo ama hoos xoog farsamo, waa mid aad u badan. si fudud looga sooci karo xabagta epoxy-ga taasoo keentay in suufka laga saaro ama naxaasta laga saaro iyo arrimo kale.

2. Saamaynta xaaladaha kaydinta guddiga wareegga

Ay saamaysay cimilada ama kaydinta waqti dheer ee meel qoyan, nuugista qoyaanka guddiga PCB waxay keenaysaa qoyaan aad u badan, si loo gaaro saamaynta alxanka ee la rabo, alxanka balastar si loo magdhabo kulaylka la qaaday sababtoo ah uumiga qoyaanka, heerkulka alxanka iyo waqtiga waa in la kordhiyaa, xaaladaha alxanka sida ay u nugul yihiin in ay sababto guddiga wareegga copper bireed iyo epoxy delamination resin, sidaas warshad processing PCB waa in fiiro gaar ah u huurka deegaanka marka kaydinta guddiga PCB ah.

3. Alxanka dhibaatooyinka alxanka birta

adhesion guddiga PCB General kulmi kartaa alxanka caadiga ah, ma jiri doonto pad off ifafaale, laakiin alaabta elektarooniga ah guud ahaan waa suurtagal in la dayactiro, dayactirka guud ahaan loo isticmaalo dayactirka alxanka birta, ay sabab u tahay heerkulka sare ee maxaliga ah ee birta alxanka inta badan gaadho 300- 400 ℃, taasoo keentay heer kul sare oo degdeg ah oo maxalli ah oo suuf ah, alxanka xabagta ee ka hooseeya foil naxaasta heerkulka sare ayaa dhacaya, muuqaalka suufku wuu deminayaa.Burburinta birta sidoo kale way fududahay in lagu iibiyo madaxa birta si lama filaan ah ee xoogga jireed ee saxanka alxanka, taas oo sidoo kale keenta sababta suufka.

TilmaamahaNeoDen IN12C Refow Foornada

1. Nidaamka sifaynta qiiqa alxanka ee la dhisay, sifeynta waxtarka leh ee gaaska waxyeelada leh, muuqaalka quruxda badan iyo ilaalinta deegaanka, in ka badan oo la jaan qaada isticmaalka jawiga sare.

2. Nidaamka xakamaynta ayaa leh sifooyinka isdhexgalka sare, jawaab celinta waqtiga, heerka guuldarada hooseeya, dayactirka fudud, iwm.

3. Naqshadaynta moduleka kuleylka gaarka ah, oo leh xakamaynta heerkulka saxda ah ee saxda ah, qaybinta heerkulka isku midka ah ee aagga magdhowga kulaylka, waxtarka sare ee magdhowga kulaylka, isticmaalka tamarta hoose iyo sifooyinka kale.

4. Naqshadeynta ilaalinta kuleylka kuleylka, heerkulka qolofka ayaa si wax ku ool ah loo xakameyn karaa.

5. Waxa uu kaydin karaa 40 fayl oo shaqaynaya.

6. Ilaa 4-way soo bandhigida waqtiga-dhabta ah ee guddiga PCB ee qalooca alxanka dusha sare.

7. khafiif ah, yaraynta, naqshadaynta warshadaha xirfadeed, xaaladaha codsiga dabacsan, bini'aadanti badan.

8. Badbaadinta tamarta, isticmaalka tamarta yar, shuruudaha sahayda korontada oo yar, korontada caadiga ah ee rayidka ah ayaa buuxin karta isticmaalka, marka la barbardhigo alaabta la midka ah sannadkii waxay badbaadin kartaa kharashka korontada ka dibna iibso 1 cutub oo alaabtan ah.
