PCB Ci gaban tawada ta solder

Domin inganta ingancin walda da gujewa lalacewar sassan da basa buƙatar yin walda yayin samarwa PCB, ana buƙatar kiyaye waɗannan ɓangarorin tare da toshe tawada. Ci gaban tawada PCB yana da alaƙa da fasahar kayan aiki, yanayin walda da buƙatun layi. Tare da ci gaba mai yawa na PCB da bayyanar fasahar walda ba tare da gubar ba, ana gabatar da sabbin buƙatun don mai narkewa don daidaita ɗanɗano tawada kuma ya sa ya cika buƙatun ink jet bugu mai ƙyalli mai ƙyalli. Tawada mai siyar da PCB yana da matakai huɗu na ci gaba, daga farkon nau’in fim ɗin bushe da nau’in thermosetting sannu a hankali ya haɓaka zuwa nau’in gyaran haske na ULTRAVIOLET (UV), sannan ya bayyana tawada mai haɓaka hoto.

1. Low danko iya zama tawada-jet waldi tawada

Tare da haɓaka masana’antar lantarki, cikakkiyar fasahar lantarki da aka buga tare da hanyar ƙari yana fitowa a daidai lokacin. Tsarin hanyar ƙari yana da fa’idar adana kayan abu, kariyar muhalli, tsari mai sauƙi, da sauransu. Saboda amfani da bugun tawada kamar babban hanyar fasaha, akwai sabbin buƙatu don kaddarorin tawada da kayan jiki, galibi ana bayyana su kamar:

(1) sarrafa danko tawada, don tabbatar da cewa ana iya fesa shi gabaɗaya ta bututun ruwa, don hana toshe ya hadu

2. FPC waldi tawada

Tare da haɓaka masana’antar PCB, buƙatar FPC tana haɓaka cikin sauri, kuma ana gabatar da sabbin buƙatun don kayan da suka dace. Saboda waya ta tagulla akan falon flexo yana da sauƙin oxidize, kayan juriya na walƙiya na waya ta flexo ya zama wurin bincike. Fim ɗin juriya na gargajiya yana nuna ƙwanƙwasawa bayan warkewa kuma bai dace da fassarar hoto ba. Sabili da haka, mabuɗin don magance matsalar shine gabatar da sashi mai sassauƙa a cikin tsarin resin gargajiya da kiyaye aikin walda na asali. Ink yana da kwanciyar hankali na ajiya mai kyau, zai iya zama mai narkewa sosai a cikin maganin carbonate sodium, maganin ammoniya, injin sarrafa fim, thermal, acid da kaddarorin lalata alkali sun cika buƙatun da suka dace.

Don rage gurɓatattun abubuwa masu narkar da ƙwayoyin cuta a cikin tsarin sarrafa PCB da rage tasirin kaushi a kan muhallin, tawada takunkumi ta sannu a hankali ta haɓaka daga tsarin ci gaban garkuwar jiki don narkar da ci gaban ruwan alkaline, kuma a cikin ‘yan shekarun nan, ya haɓaka zuwa ruwa fasahar ci gaba. A lokaci guda, don biyan buƙatun fasahar walda ta kyauta don fim ɗin juriya, inganta juriya ga babban aikin zafin jiki.

4. LED tare da babban tunani farar takin mai siyarwa

TaiyoInk ya fara nuna farar allurar da ke toshe tawada don kunshin LED a 2007. Idan aka kwatanta da tawada mai siyar da kayan gargajiya, farar aljihun yana buƙatar warware matsalolin canza launi da haɓaka tsufa sanadiyyar bayyanar dogon lokaci zuwa tushen haske. Tawada mai siyar da epoxy na gargajiya saboda tsarin kwayoyin da ke ɗauke da zobe na benzene, haske na dogon lokaci yana da sauƙin haifar da canza launi. Don tushen haske na LED, an rufe murfin juriya a ƙasa da kayan luminescent, don haka ya zama dole don haɓaka ingantaccen tunani na rufin juriya na siyarwa zuwa haske, sannan haɓaka hasken tushen haske. Wannan yana gabatar da sabon ƙalubale ga binciken abubuwan walda na juriya.

The bincike na solder tawada ne ko da yaushe a wuya batu a PCB masana’antu. Tare da da’irar bugu daga hanyar cirewa a hankali zuwa hanyar ƙari, bugun inkjet a matsayin babban hanyar fasaha na ƙarin tsari, danko na tawada mai siyarwa, thixotropy da reactivity sun gabatar da buƙatu mafi girma; Tallace-tallacen fasahar walda ba tare da gubar ba ta gabatar da sabbin buƙatu don tsananin juriya na fim ɗin solder, haɓaka sabon jujjuyawar mai siyarwa cikin gaggawa yana buƙatar ɗimbin masu bincike, kuma bincike na tawada mai siyarwa yana kan tashi, wanda ke da girma m.
