1. OST OF PCB: OSP, HASL, Jagorar Tin, Azurfa, Azurfa, Alain Zinare don Comple na Zinariya, Edepig ...
OSP: araha mai tsada, kyakkyawan yanki, yanayin hamada, ɗan gajeren lokaci, fasahar muhalli, mai kyau waldi, mai santsi ...
HASL: Yawancin lokaci yana da mulla'ayers Hdi PCB samfurori (4 - 46 yadudduka), masana'antu da yawa sun yi amfani da manyan kamfanoni da raka'a Aerospace.
Jagora na zinariya: Haɗin kai ne tsakanin ƙwaƙwalwar ƙwaƙwalwa da guntu.
Jagorar zinare masana ta da yawa daga cikin lambobin gudanar da zinari, waɗanda ake kira "yatsa na zinariya" saboda tsarin-fina-finai na zinariya. Yunkurin zinare da gaske yana amfani da tsari na musamman don suturar da zinariya, wanda yake matuƙar tsayayya da hadawa da hankali. Amma farashin zinare yana da tsada, ana amfani da tin a yanzu don maye gurbin ƙarin ƙwaƙwalwar ajiya. Daga karni na ƙarshe 90 s, kayan aikin fara yada, memelard, da na'urorin haɗi na Server, don haka farashin yana da ɗan tsada kaɗan.
2. Me yasa ake amfani da kwamitin da aka sanya gwal?
Tare da hadewa na ici mafi girma kuma mafi girma, ƙafa ƙafa kaɗan da yawa. Duk da yake a tsaye tin spraying tsari yana da wuya busa mai kyau walding pad lebur, wanda ya kawo wahala ga Smt hawa; Bugu da kari, da shelf rayuwar tin spraying farantin yana da gajeru. Koyaya, farantin zinari yana warware waɗannan matsalolin:
1.) Don fasaha ta ƙasa, musamman ga 0603 da 0402 da kuma ingancin kuɗaɗen sikelin yana da tasiri kai tsaye da ƙimar ƙwararrun mai siyarwa, a bayan farantin tebur da ƙananan kayan kwalliya yana da tasirin ƙwararrun masana'antar.
2.) A lokaci na cigaban, tasirin dalilai kamar kayan sayowar sukan kasance da yawa, amma sau da yawa dole ne a jira 'yan makonni ko ma da yawa. Bayan haka, PCB mai launin zinare a cikin digiri na farashin farashin samfurin idan aka kwatanta da faranti na pewter
Amma tare da more da more m wiring, layin layi, spacing ya kai 3-4mil
Saboda haka, yana kawo matsalar gajeriyar hanyar waya na gwal: tare da kara siginar, tasirin watsa siginar sigina saboda tasirin fata ya zama mafi yawa
(Tasirin fata: Babban mitar tana canza yanayin halin yanzu, na yanzu zai iya maida hankali a kan saman waya ta gudana. Zurfin fata yana da alaƙa da mita.)
3. Me yasa amfani da PCB mai nutsuwa?
Akwai wasu halaye don babban PCB din wasan kwaikwayon na da ke ƙasa:
1.) Tsarin crystal da aka kafa ta hanyar nutsuwa da kayan kwalliya ta bambanta, launin zinari zai zama mafi kyau fiye da kayan kwalliya na zinari zai fi gamsuwa. Sannan damuwa na farantin zinari ya fi sauƙi a sarrafa, wanda ya fi dacewa da aiki da samfuran. A lokaci guda kuma saboda zinari ya fi zinariya fiye da zinariya, farantin zinari ba sa sawa - yatsan gwal.
2.) Gwal mai nutsarwa yana da sauƙin auna fiye da kayan zinari, kuma ba zai haifar da welding mara kyau da gunaguni na abokin ciniki ba.
3.) Za a iya samun zinare a kan walding pcb, watsa siginar a cikin tasirin fata shine a cikin siginar fata, shima ba zai haifar da siginar da waya ba don zinari. Mai siyarwa a da'irar ya fi ƙarfin ƙarfi tare da jan ƙarfe.
4.) Tsarin kwanciyar hankali na zinari shine denser fiye da suturar zinare, yana da wuya a haifar da haushi
5.) Ba za a sami sakamako ba a kan ragi yayin da aka yi diyya
6.) The Cire da rayuwar Ma'aikata na zinare yana da kyau kamar na farantin gwal.
4. Nutsar da zinari vs na zinariya
Akwai nau'ikan fasahar da ke tattare da zinare guda biyu: ɗaya shine kayan zinari na zinari, ɗayan kuma yana nutsar da zinari.
Don tsarin shirya gwal, tasirin tin an rage shi sosai, kuma sakamakon zinari ya fi kyau; Sai dai idan masana'anta yana buƙatar ɗauri, ko kuma yawancin masana'antun za su zaɓi tsarin tafiyar da zinari!
Gabaɗaya, ana iya raba jiyya na PCB zuwa nau'ikan masu zuwa: Tsarin zinare (onplating, kayan kwalliya, kayan kwalliya, kayan kwalliya, kayan kwalliya, kayan kwalliya na fru, waɗanda suke ɗaukar kayan jeri na FR4 ko kuma Rosin shafi jiyya; A kan tin matalauta (cin talm) wannan idan cire masana'antun masana'antun masana'antu da dalilan sarrafa kayan abu.
Akwai wasu dalilai na matsalar PCB:
1.Duko Bugawa PCB, ko akwai sakamakon fim na fim a kan kwanon rufi, zai iya toshe sakamakon tin; Wannan jarabawar ruwa ta iya tabbatar da wannan
2.Ka iya yin amfani da matsayin kwanon kwanon rufi na iya haɗuwa da abubuwan ƙira, wato, za a iya tsara welding ɗin don tabbatar da goyon bayan sassan.
3.Za walƙewa bata gurbata, wanda za'a iya auna shi ta hanyar gurbataccen ion.
Game da farfajiya:
Aikin zinare, zai iya yin lokacin ajiya na PCB ya fi tsayi, kuma ta hanyar yanayin zafin yanayi a waje), gabaɗaya, ana iya ajiye shi kusan shekara guda; Hasl ko jagoranci kyauta kyauta jiyya na biyu, OSP kuma, jiyya na farfajiya guda biyu don kula sosai, da bukatar amfani da takarda mai yawa na sulfur! Kuma adana shi na kusan watanni uku! A kan tasirin tin, zinari, osp, tin fessa a zahiri game da wannan, masana'antun galibi ne don la'akari da farashin farashi!
