Solder Zvinokambaira Zvinokonzera & Zvigadziriso zvePTFE Yakakwira-Tembiricha Tepi

Senyanzvi sosi inogadzira PTFE yakakwira-tembiricha machira, Jiangsu Aokai New Materials inogovera indasitiri yehunyanzvi. Insights.MuPCB inopisa mhepo solder kuyera, goridhe plating uye kunyudza goridhe maitiro, solder inokambaira painodzivirira mipendero yePTFE high-temperature tepi inonyanya kukonzerwa nekubatanidzwa kwekutadza kwemuviri kwetepi uye kunyanyisa maitiro nharaunda.

I. Zvinokonzera Kukambaira Kwemushonga

Edge warping yePTFE yepamusoro-tembiricha tepi ichigadzira mapeji Panguva yekugadzirwa kwepamusoro-tembiricha, simba rekunamatira re tepi rinoderera sezvo tembiricha inokwira. Kana iyo yekunamatira isingakwane kupikisa kushushikana kwekupisa, tepi mipendero inotenderera zvishoma uye inogadzira capillary gaps, ichibvumira mvura solder kupinda mukati.

Wicking mhedzisiro uye solder dhamu kuunganidza Solder inowanzokwira yakananga kunzvimbo dzine tembiricha yepamusoro. Kana iyo nzvimbo yakadzivirirwa iri pakupisa kwakanyanya, mvura solder inokwira ichikwira kumusoro pamwe nemakapu etepi mune yakajairika wicking. effect.Uyezve , yakanyanyisa gobvu PTFE tepi ichaita nhanho kumicheto, zvichiita kuti solder iunganidze kuita solder dhamu, izvo zvinowedzera kuwedzera solder zvinokambaira.

Mismatched material quality yePTFE high-temperature tepi The adhesive layer ye inferior PTFE tepi inogara ichiyerera, kuparara uye inonamira zvakasara pakupisa kwepamusoro. Haisi kungokuvadza chivharo chekudzivirira, asiwo inosvibisa mapedhi, ichiwedzera zvakanyanya njodzi ye solder zvinokambaira.

Zvinosvibisa zvichinzvenga tepi yePTFE Kunyange kana tepi yacho isina kusimba, kuputika nekupfapfaidza mabeads asara muPCB vias, kana twunhu tudiki tunogadzirwa neflux vaporization panguva yereflow soldering, inogona kupinda kana kudarika nzvimbo yekudzivirira uye kukonzera kusvibiswa.

Yakashata lamination uye muitiro fluctuation Kutadza kuchenesa nhovo pamusoro kana kusakwana kudzvanya panguva tepi chikumbiro achasiya mikaha nokuda solder penetration.Excessively nokukurumidza tembiricha kukwira panguva reflow soldering zvinopinza anowedzera solder fluidity, zvichiita nyore kutyora muganhu PTFE tepi.

Kunyorova kwenzvimbo dzegoridhe dzeplating kuri kuwedzera dambudziko rakaputirwa negoridhe uye kunyudzwa nzvimbo dzegoridhe dzinoratidza kunyorova kwekutengesa. Kamwe solder inobata nzvimbo yegoridhe, inopararira nokukurumidza pamwe chete nemicheto yematepi, zvichiita kuti pave nezvinokambaira zvakakura kudarika OSP uye zvinowanzopisa mhepo inopisa solder maitiro.

II. Solutions: Yakarongeka Yechikumbiro Chirongwa cheYakakwirira-Quality PTFE Tape

Sarudza zvigadzirwa zvinokwanisa uye gadzirisa lamination operation Gamuchira yepamusoro-soro PTFE yakakwirira-tembiricha tepi yakanyatsogadzirirwa PCB yepamusoro-tembiricha maitiro, ine tembiricha kuramba 250 ~ 260 ℃ kusangana nemutobvu-isina kugadzirwa zvinodiwa.Chenesa nhovo pamusoro neisopropanol pamberi chikumbiro nechokwadi chakazara chakakodzera pasina kumucheto warping kana mikaha. Pfeka magirovhosi panguva yekushanda kudzivirira kusvibiswa kwegirisi.

Dzivirira kupfachuka kwebead kubva pakupaza nekudzivirira Adopt low-splashing solder paste formula uye shongedza reflow tembiricha curve. Preheating yakakwana inodzivirira mhirizhonga inonyungudutsa vaporization uye inoderedza njodzi yediki diki solder mabhero achipaza nepakati tepi shielding.

Simbisa kudhinda uye midziyo yekuchenesa manejimendi Chenesa stencil mushure mekudhinda yega 2-3 PCB, uye tora yakaoma yekupukuta + vacuum yekuchenesa modhi kudzivirira solder paste kupfapfaidza panzvimbo yetepi.Gara uchibvisa yakasara solder poda pamushini wokudhinda, mounter tracks uye zvigadziriso kuti ubvise kusvibiswa kwechipiri.

Yakasimba inopinda uye inogadzirisa kunaka kwekutonga kuti iite zvinhu zvinogumira Inoda vatengesi vePCB kuti vape vanokwanisa plugging quality zvitupa kuti vave nechokwadi zvizere akazadzwa vias uye kudzivirira yakavanzwa solder mabhedhi kubva nokunzvenga nhovo tepi.Ronga random solderability kuongorora kuti goridhe-plated mapuranga. Kamwe matambudziko akadai seatete goridhe layer uye nickel corrosion awanikwa, vhara zvigadzirwa zvakaremara kudzivirira zvakanyanya solder zvinokambaira zvinokonzerwa neabnormal solder kupararira.

Gamuchira mamwe maitiro ekudzikisa kutsamira pamatepi Kana kugadzirwa kwechigadzirwa kuchibvumidza, shandisa mabatirwo akasarudzika, akadai sekuisa goridhe remuno chete pamapadhi uye mushure mekugadzirisa zvigunwe zvegoridhe. Izvi zvinobvisa kudiwa kwekudzivirira kwemupendero nePTFE tepi uye zvine musoro kugadzirisa iyo solder zvinokambaira nyaya.

Sarudzo ine musoro, yakamisikidzwa lamination uye yakazara-maitiro ekubatana kutonga kwePTFE yakakwirira-tembiricha tepi ndiwo makiyi akakosha ekubvisa zvinokambaira solder. Kugadzirisa ruzivo rwekushandisa kunogona kunyatso kuvandudza goho rekugadzira uye kuderedza mutengo wekugadzirisa zvakare.

Izvo zviri pamusoro pehunyanzvi zvemukati zvinopihwa neJiangsu Aokai New Materials Technology Co., Ltd.

Kana iwe uchida zvakadzama parameters, makesi ekushandisa uye zvigadziriso zvakagadziridzwa zvePTFE yakakwirira-tembiricha jira, PTFE yakakwirira-tembiricha tepi, PTFE mesh bhandi, isina musono fusing muchina bhandi, single-sided PTFE yakavharwa jira, yakakwirira-tembiricha isingachinji bhandi uye fiberglass jira, ndapota taura nesu:
