Zvikamu zveChip zvidiki uye zvidiki zvisina anotungamira kana mapfupi madonhwe, ayo akaiswa zvakananga paPCB uye akakosha maturusi e.surface assembly technology.Zvikamu zveChip zvine zvakanakira saizi diki, huremu huremu, yakanyanya kuisirwa density, kuvimbika kwakanyanya, yakasimba seismic kuramba, yakanaka high frequency maitiro, yakasimba anti-kupindira kugona, asiwo nekuda kwevhoriyamu yavo idiki, kutya kupisa, kutya kubata. , mamwe mapini ekutungamirira akawanda, zvakaoma kuparadzanisa, izvo zvinounza matambudziko makuru pakugadzirisa.
Kazhinji disassembly maitiro ndeaya anotevera.Zvakakosha kucherechedza kuti: munharaunda yekupisa kwenzvimbo, tinofanira kudzivirira magetsi emagetsi, uye simba resimbi yemagetsi uye ukuru hwemusoro wesimbi inofanira kunge yakakodzera.
I. Nzira yekubvisa mhangura mesh nzira
Suction copper net inogadzirwa newaya yakanaka yemhangura yakarukwa kuita bhandi reticulated, inogona kutsiviwa nesimbi inodzivirira tambo yetambo kana mamwe tambo dzewaya yakapfava.Paunenge uchishandiswa, vhara tambo pa-multi-pini uye isa rosin doro flux.Kupisa nesimbi yesimbi, uye kudhonza waya, solder patsoka inoshambadzirwa newaya.Cheka waya ine solder uye dzokorora kakawanda kuti utore solder.Iyo solder papini inoderera zvishoma nezvishoma kusvikira pini yechikamu ichiparadzaniswa kubva pabhodhi rakadhindwa.
II.Yakakosha simbi musoro disassembly nzira yekusarudza uye kutenga yakakosha "N" yakaumbwa musoro wesimbi, iyo yekupedzisira notch hupamhi (W) uye kureba (L) inogona kutariswa zvichienderana nehukuru hwezvikamu zvakaparadzaniswa.Musoro wesimbi wakakosha unogona kuita solder yepini inotungamira pamativi ese ezvikamu zvakanyungudutswa zvinyunguduke panguva imwe chete, kuitira kufambisa kubviswa kwezvikamu zvakabviswa.Nzira yekuzvigadzira yemusoro wesimbi ndeyekusarudza chubhu tsvuku yemhangura ine dhayamita yemukati inoenderana nekunze kwemusoro wesimbi, sunga imwe mugumo neipi (kana sando) uye kuboora gomba diki, sezvakaratidzwa mumufananidzo 1 ( a).Zvadaro mahwendefa maviri emhangura (kana kuti machubhu emhangura akachekwa kureba uye kupepetwa) anoshandiswa kuagadzira kusvika pakukura kwakafanana nezvikamu zvakabviswa, uye maburi anoboorwa, sezvinoratidzwa mumufananidzo 1 (b).Chiso chekupedzisira chendiro yemhangura chaive chakati sandara, chakakwenenzverwa chakachena, uye pakupedzisira chaunganidzwa muchimiro sezviri kuratidzwa muMufananidzo 1 (c) nemabhaudhi, ayo akaiswa pamusoro wesoldering.Musoro we soldering unogona kushandiswa nekupisa uye kunyura tini.Kune rectangular flake components ine maviri solder spots, as long as the soldering iron head is knocked into flat shape, kuitira kuti hupamhi hwechiso chekupedzisira huenzane nehurefu hwechikamu, nzvimbo mbiri dzekutengesa dzinogona kupisa uye kunyungudutswa panguva imwe chete. , uye zvikamu zveflake zvinogona kubviswa.
III.Iyo solder yekuchenesa nzira
Kana iyo solder ichipisa ne-antistatic soldering iron, solder inocheneswa nebhurashi remazino (kana bhurashi remafuta, brashi yependi, nezvimwewo), uye zvikamu zvinogonawo kukurumidza kubviswa.Mushure mokunge zvikamu zvabviswa, bhodhi rakadhindwa rinofanira kucheneswa munguva kudzivirira pfupi pfupi yezvimwe zvikamu zvinokonzerwa nemararamiro ematini.
