4 lakabka PCB oo leh farta dahabka ah nidaamka maqalka dijitaalka ah

Wax soo saarka wax soo saarka

Iyada oo ah alaab-qeybiyeyaal ka mid ah teknolojiyadda PCB ee PCB, xulashooyinka waqtiga hogaaminta, waxaan heysanaa xulasho agab heer sare ah oo ay tahay xayndaab ballaaran ee noocyada noocyada kala duwan ee PCB-da ay had iyo jeer guriga ku jiraan.

Shuruudaha loogu talagalay waxyaabaha kale ama agab gaar ah ayaa sidoo kale lagu buuxin karaa inta badan kiisaska, laakiin, waxay kuxirantahay shuruudaha saxda ah, ilaa 10 maalmood oo shaqo ayaa loo baahan karaa si loo soo iibsado maaddada.

Na soo xiriir oo ka wada hadal baahiyahaaga mid ka mid ah iibkayaga ama kooxda 'CAM'.

Qalabka caadiga ah ee lagu qabtay:

Dhumucda cufnaanta ee lakabyada gudaha: heerka - 18μm iyo 35 μm,

Markaad codsatid 70 μm, 105μm iyo 140μm

Nooca shey: fr4

TG: qiyaastii. 150 ° C, 170 ° C, 180 ° C

εr 1 MHz: ≤55,4 (Caadi ahaan: 4,7) inbadan ayaa la heli karaa haddii la codsado

Gaari xirid

4-ta-lakabka ee la daabacay

Dhammaan lakabyadan waxaa loo isticmaalaa marinnada calaamadaha.

Labadiijibbaarane laba-geesood ah ayaa jiifa gudaha xudunta waxaana inta badan loo adeegsadaa maadaama ay u adeegsadaan maadaama ay badanaa lagu tilmaamo marinnada calaamadaha.

Si fudud ugu hadalka 4-lakab lakabka PCB wuxuu heystaa 2 of Singlea VCC iyo lakabka dhulka.

Qodobbada muhiimka ah ee loogu talagalay iibsashada PCB

Iibsadayaasha warshadaha elektaroonigga ah badankood waxay ku wareereen qiimaha PCBs. Xitaa dadka qaar ee khibradda badan ee khibradda badan ee soo iibsiga PCB ayaa laga yaabaa inaysan si buuxda u fahmin sababta asalka ah. Xaqiiqdii, qiimaha PCB wuxuu ka kooban yahay qodobbada soo socda:

Marka hore, qiimayaashu way kala duwan yihiin sababtoo ah agabyada kala duwan ee loo isticmaalo PCB.

Qaadashada lakab laba lakab ah ee caadiga ah PCB tusaale ahaan, yareynta wuxuu ku kala duwan yahay FR-4, Cem-3, iwm. Dhumucdu u dhumucdu waxay ku kala duwan tahay 0.5oz ilaa 6oz, oo dhammaantood sababay farqi weyn u dhexeeya. Qiimaha 'Soldermaksk' ayaa sidoo kale ka duwan qalabka heerkulka caadiga ah ee qarashka ah iyo sheyga cagaaran ee cagaaran.

Midda labaad, qiimayaashu way kala duwan yihiin sababtoo ah geedi socod soo-saar kala duwan.

Nidaamyada wax soo saarka ee kaladuwan ayaa ka dhasha kharashyo kaladuwan. Sida guddiga dahabka ah ee dahabka iyo guddiga tin-plage, qaabka socodka iyo xargaha khadadka shaashadda ee xarkaha iyo khadadka filimka qalalan waxay sameyn doonaan kharashyo kaladuwan, taasoo dhalisay kala duwanaanta qiimaha.
