• I. PCB Tswj Specification

• 1. PCB unpacking and storage (1) PCB board kaw thiab unopened tuaj yeem siv ncaj qha online nyob rau hauv 2 lub hlis ntawm hnub tsim khoom (2) PCB board manufacturing hnub yog nyob rau hauv 2 lub hlis, thiab lub unpacking hnub yuav tsum tau cim tom qab unpacking.(3) PCB board manufacturing hnub yog nyob rau hauv 2 lub hlis, tom qab unpacking, nws yuav tsum tau nyob online thiab siv nyob rau hauv 5 hnub
  2. PCB Postcure
• (1) Yog tias PCB raug kaw thiab tsis ntim rau ntau tshaj 5 hnub hauv 2 lub hlis ntawm hnub tsim khoom, thov kho tom qab 120 ± 5 ° C rau 1 teev(2) Yog tias PCB ntau tshaj 2 lub hlis txij li hnub tsim khoom, thov kho nws tom qab 120 ± 5 ° C rau 1 teev ua ntej mus online
  (3) Yog tias PCB yog 2 mus rau 6 lub hlis dhau los ntawm hnub tsim khoom, thov kho tom qab ntawm 120 ± 5 ° C rau 2 teev ua ntej mus online
  (4) Yog tias PCB yog 6 lub hlis mus rau 1 xyoo dhau los ntawm hnub tsim khoom, thov rov kho nws ntawm 120 ± 5 ° C rau 4 teev ua ntej mus online
  (5) Lub PCB ci yuav tsum tau siv li ntawm 5 hnub (muab tso rau hauv IR REFLOW), thiab PCB yuav tsum tau rov kho dua rau lwm teev ua ntej nws tuaj yeem siv online.
  (6) Yog tias PCB ntau tshaj li ib xyoos txij li hnub tsim khoom, thov rov kho nws ntawm 120 ± 5 ° C rau 4 teev ua ntej yuav mus online, thiab xa mus rau lub Hoobkas PCB kom rov tshuaj tin ua ntej mus online.3. PCB postcure method(1) Cov PCBs loj (16 PORTs thiab siab dua, suav nrog 16 PORTs) tau muab tso rau kab rov tav, ib pawg ntawm txog 30 daim, qhib qhov cub li ntawm 10 feeb tom qab lub ci tiav, tshem tawm PCB, thiab txias nws kab rov tav (xav tau nias lub anti-phaj bay fixture)

  (2) Cov PCBs me thiab nruab nrab (nrog rau 8PORTs hauv qab 8PORT) tau muab tso rau kab rov tav. Qhov siab tshaj plaws ntawm ib pawg yog 40 daim. Tus naj npawb ntawm hom ntsug yog unlimited. Qhib lub qhov cub thiab tshem tawm PCB li ntawm 10 feeb tom qab kev kho mob tiav. Banwan fixture)

II. Kev khaws cia thiab tom qab kev kho mob ntawm PCBs hauv thaj tsam sib txawv
Lub sijhawm khaws cia tshwj xeeb thiab tom qab ntsuas kub ntawm PCB tsis yog tsuas yog cuam tshuam nrog lub peev xwm tsim khoom thiab cov txheej txheem tsim khoom ntawm PCB cov chaw tsim khoom, tab sis kuj muaj kev sib raug zoo nrog cheeb tsam.

Lub PCB ua los ntawm OSP txheej txheem thiab cov txheej txheem kub immersion ntshiab feem ntau muaj lub neej txee ntawm 6 lub hlis tom qab ntim, thiab nws feem ntau tsis pom zoo kom ci rau OSP txheej txheem.

Kev txuag thiab ci lub sij hawm ntawm PCB muaj ntau yam ua rau thaj tsam. Nyob rau sab qab teb, cov av noo feem ntau hnyav dua, tshwj xeeb tshaj yog nyob rau hauv Guangdong thiab Guangxi. Nyob rau lub Peb Hlis thiab Plaub Hlis ntawm txhua xyoo, yuav muaj huab cua "rov qab mus rau sab qab teb", uas yog huab cua thiab los nag txhua hnub. Nruam, nws tau ntub heev thaum lub sijhawm no. PCB raug rau huab cua yuav tsum tau siv li ntawm 24 teev, txwv tsis pub nws yooj yim rau oxidize. Tom qab qhib ib txwm, nws yog qhov zoo tshaj los siv nws hauv 8 teev. Rau qee qhov PCBs uas yuav tsum tau ci, lub sijhawm ci yuav ntev dua. Hauv cov cheeb tsam sab qaum teb, huab cua feem ntau qhuav, lub sijhawm khaws cia PCB yuav ntev dua, thiab lub sijhawm ci tuaj yeem luv dua. Qhov ci kub yog feem ntau 120 ± 5 ℃, thiab lub sijhawm ci yog txiav txim siab raws li qhov xwm txheej tshwj xeeb.
