Dej Chillers hauv PCB Manufacturing

ANYDA tau lees paub zoo tias yog ib qho ntawm cov ua lag luam ntawm cov dej chillers hauv pcb manufacturing hauv Suav teb. Tag nrho cov khoom rau kev muag khoom yog tsim los ntawm peb cov kws tshaj lij cog. Yog tias koj txaus siab rau nws, thov pub dawb kom tau txais cov khoom siv thev naus laus zis siab - nrog tus nqi sib tw los ntawm peb.

Daim ntawv thov kev lag luam dej chillers hauv PCB (Printed Circuit Board) kev tsim khoom:

PCB kev tsim khoom muaj ntau yam kev kub siab -cov txheej txheem kub uas yuav tsum tau tswj qhov kub thiab txias kom ntseeg tau tias lub rooj tsavxwm zoo, qhov ruaj khov, thiab kev ua haujlwm ntau lawm. Muaj dej chillers ua lub luag haujlwm tseem ceeb thoob plaws hauv txheej txheem PCB fabrication.

1.Drilling thiab Routing (Spindle Cooling)

PCB drilling thiab routing tshuab siv siab - spindles ceev uas tig ntawm 20,000 - 300,000 RPM. Cov spindles no tsim cov cua kub tseem ceeb, uas tuaj yeem ua rau thermal expansion ntawm spindle ncej, ntxov ntxov bearing hnav thiab spindle tsis ua hauj lwm thiab burr tsim thiab ntxhib qhov phab ntsa. Chiller tuaj yeem tswj xyuas qhov kub ntawm qhov ntxaiv rau qhov sib xws ntawm lub qhov taub thiab qhov tseeb ntawm txoj haujlwm.

2. Lamination (Multilayer PCB nias)

Multilayer PCBs yog tsim los ntawm stacking tooj liab- clad laminates thiab prepreg (semi-kho resin) nplooj ntawv, ces nias lawv nyob rau hauv kub thiab siab. Tom qab lub voj voog nias, cov pawg yuav tsum tau txias rau hauv kev tswj xyuas kom tsis txhob muaj kev sib tsoo los yog delamination, kom ntseeg tau tias cov dej ntws sib txawv thiab kev sib txuas thiab txo lub sijhawm voj voog kom siab dua.

Chiller ntawm no tuaj yeem muab cov dej txias rau cov cua txias ntawm cov xovxwm hydraulic, pab tswj cov cua txias (piv txwv li, 5℃- 10℃ib feeb) thiab ua haujlwm hauv tandem nrog rhuab platens rau lub voj voog xovxwm.

3. txheej txheem etching

Nyob rau hauv ob qho tib si sab hauv thiab txheej txheej etching, tshuaj etchants (cupric chloride, ferric chloride, alkaline ammonia) yog siv los tshem tawm pliaj tooj liab. Etching cov tshuaj tiv thaiv yog exothermic, thiab yog hais tias qhov kub thiab txias etching nce siab dhau lawm, etching yuav nruj heev, ua rau undercutting thiab nplua kab poob, etchant chemistry degrades sai, sidewalls ua tsis sib xws, txo cov txiaj ntsig zoo -pitch designs

Dej chiller tuaj yeem tswj xyuas qhov kub thiab txias ntawm qhov zoo tshaj plaws (feem ntau yog 45℃- 55℃rau alkaline etching), tshem tawm cov tshuaj tiv thaiv kub tsis tu ncua thiab ua kom muaj qhov sib npaug thiab sib npaug ntawm tag nrho cov vaj huam sib luag.

4. Kev tsim kho thiab tshem tawm

Photoresist tsim thiab stripping daws yog qhov kub thiab txias -sensitive. Yog tias qhov kub thiab txias hloov pauv, qhov kev loj hlob tsis tiav tawm ntawm qhov seem ntawm photoresist, dhau - kev loj hlob ua rau kab dav variations thiab stripping efficiency txo, yuav tsum tau ua ntev dua

Dej chiller tuaj yeem tswj xyuas kev tsim thiab tshem tawm da dej ntawm qhov ntsuas kub (feem ntau 25℃- 35 degree), muab kev kub ceev rov qab tom qab ntxiv cov tshuaj tshiab (da dej rov qab) thiab tiv thaiv thermal poob siab rau txheej txheej photoresist

5. Electroplating (Copper, Tin, Nickel, Kub)

Electroplating da dej ua kom sov los ntawm hluav taws xob tsis kam thiab tshuaj lom neeg. Kev tswj tsis tau qhov kub thiab txias ua rau tsis sib xws plating thickness, ntxhib los yog nodular deposits, tsis zoo pov lub hwj chim nyob rau hauv siab -yam- qhov sib piv qhov thiab ceev da dej additive decomposition

Dej chiller cools plating tso tsheb hlau luam los ntawm immersed coils los yog sab nraud tshav kub exchangers, tswj kom meej da dej kub (feem ntau 20℃- 30℃rau acid tooj liab plating) thiab enables siab tam sim no ceev ua hauj lwm yam tsis muaj overheating.

Cov txiaj ntsig ntawm Kev Siv Lub Khoos Phis Tawj PCB Chiller

1. Txhim kho cov txiaj ntsig zoo: Qhov ntsuas kub tsis tu ncua txo qhov tsis xws li qhov tsis raug sau npe, plating voids, thiab kab dav variations

2.Higher Throughput: ceev dua drilling speeds thiab txo cov xovxwm voj voog sij hawm

3. Extended Equipment Life: Spindles, motors, thiab electronics kav ntev dua nrog kev ua kom txias

4.Process Stability: Tshem tawm batch- mus rau -batch variation tshwm sim los ntawm kub drift

5. Zog Efficiency: Niaj hnub nimno inverter chillers kho lub peev xwm kom phim tiag tiag - lub sijhawm thauj khoom

Ua tib zoo xaiv cov lus qhia rau PCB Manufacturing Chillers

1.Compact recirculating chillers nrog cov lim dej huv thiab ± 0.5℃raug

2. Central chillers nrog titanium tshav kub exchangers thiab ntau qhov chaw

3.High-muaj peev xwm chillers nrog programmable kub ramp-down profiles

4. Modular chiller tshuab uas tuaj yeem nthuav dav raws li kev tsim khoom loj tuaj

Hauv cov ntsiab lus, cov dej chillers muaj cov khoom siv tseem ceeb hauv kev tsim PCB, tsis yog ib qho khoom siv xwb. Lawv ncaj qha cuam tshuam rau lub rooj tsavxwm zoo, kev ua haujlwm ceev, thiab kev ntseeg siab ntawm cov cuab yeej siv, ua kom zoo chiller xaiv thiab kho qhov tseem ceeb ntawm txhua qhov chaw tsim khoom PCB.
