Mazhinji emagetsi anogadzirwa nemagetsi nhasi anogadzirwa pachishandiswa tekinoroji yepamusoro kana SMT, sekudanwa kwayinowanzoitwa. Kwete pasina chikonzero! In addition to providing many other advantages, SMT PCB inogona kuenda kure nzira yekumhanyisa pcb yekugadzira nguva.

Pamusoro kugomo tekinoroji

Basic Surface Mount Technology (SMT) The basic through-hole manufacturing concept continues to provide significant improvements. Nekushandisa SMT, iyo PCB haifanirwe kudhonzwa mairi. Pane kudaro, izvo zvavanoita ivo vanoshandisa solder paste. Pamusoro pekuwedzera yakawanda yekumhanyisa, izvi zvinorerutsa maitiro. Nepo SMT yekumisikidza zvinhu zvingave zvisina simba rekupfuura-gomba kusimudzira, ivo vanopa zvimwe zvakawanda zvakanaka kuti vabvise iri dambudziko.

Surface gomo tekinoroji inoenda kuburikidza ne5-nhanho maitiro seinotevera: 1. Kugadzirwa kwePBBB – Iyi inhanho yechipiri apo iyo pcb inogadzira masisitimu esolder. Iyo solder inoiswa padhidhi, ichibvumira kuti chinhu icho chigadziriswe kune redunhu bhodhi 3. Nerubatsiro rwemuchina, izvo zvikamu zvinoiswa pane chaiwo majoini esoder. Bika pcb kuomesa solder 5. Tarisa uone zvakapedzwa

Misiyano pakati peSMT uye nepakati-gomba inosanganisira:

The widespread spatial problem in through-hole installations is solved by using surface mount technology. SMT inopawo dhizaini kuchinjika nekuti inopa PCB vagadziri rusununguko rwekugadzira macircuit akazvipira. The smaller component size means that more components can fit on a single board and fewer boards are required.

Zvikamu mumisheni yeSMT hazvitungamire. Ipfupi kureba kwekutungamira kwenzvimbo yepamusoro pechinhu, kudzikira kwekunonoka kwekupararira uye kwakadzikira ruzha rwekutakura.

Kuwanda kwezvikamu pachikamu cheyuniti kwakakwirira nekuti inobvumira kuti zvikamu zviiswe pamativi ese.

Iyo inokodzera kugadzirwa kwemazhinji, nekudaro ichideredza mutengo.

Kuderedza muhukuru kunowedzera kumhanya kwedunhu. Ichi ndicho chaicho chimwe chezvikonzero zvikuru vagadziri vazhinji vanosarudza nzira iyi.

Iko kunetsekana kwepasirese kwesimbi yakanyungudutswa inokwevera icho chinhu kuti chiwirirane nepad. Izvi zvinobva zvagadzirisa zvoga zvikanganiso zvidiki zvingave zvakaitika mukuiswa kwechinhu.

SMT yakaratidza kuve yakadzikama muzviitiko zvekudengenyeka kana kudedera kwakanyanya.

SMT parts usually cost less than similar through-hole parts.

Zvakakosha, SMT inogona kudzikisa zvakanyanya nguva dzekugadzira nekuti hapana kuchera kunodiwa. Uye zvakare, zvikamu zveSMT zvinogona kuiswa pachiyero chezviuru paawa, zvichienzaniswa nechepasi pechuru kuburikidza nekuiswa kwemaburi. Izvi, zvakare, zvinotungamira kune zvigadzirwa zviri kugadzirwa neanoda kumhanya, izvo zvinowedzera kuderedza nguva kumusika. Kana iwe uri kufunga yekumhanyisa pcb yekugadzira nguva, SMT ndiyo mhinduro iri pachena. Kubudikidza nekushandisa dhizaini uye gadzira (DFM) maturusi esoftware, kudiwa kwekugadzirisa uye kugadzirisazve maseketi akaomeswa kwakadzikira zvakanyanya, kuwedzera kukurumidza kumhanya uye mukana wekugadzirwa kwakaomarara.

Zvese izvi hazvireve kuti SMT haina zvipingaidzo zvakasikwa. SMT inogona kunge isingavimbike kana ichishandiswa senzira yega yekubatanidza yezvikamu zvinotarisana nekushushikana kwakanyanya. Zvinhu zvinogadzira kupisa kukuru kana kumira zvinorema zvemagetsi zvinorema hazvigone kuiswa uchishandisa SMT. Izvi zvinodaro nekuti solder inogona kusungunuka patembiricha dzakakwirira. Naizvozvo, kuisa-gomba kumisikidzwa kunogona kuramba kuchishandiswa muzviitiko zvine hunhu, zvemagetsi, uye zvekushisa zvinoita kuti SMT isashande. Pamusoro pezvo, SMT haina kukodzera kuratidzira nekuti zvikamu zvinogona kuda kuwedzerwa kana kutsiviwa panguva yechikamu chekuratidzira, uye mabhodhi akakwirisa ezviumbwa anogona kunge akaoma kutsigira.

Shandisa iyo SMT

Nemabhenefiti akasimba anopihwa neSMT, zvinoshamisa kuti ave akakosha dhizaini uye yekugadzira standard. Basically they can be used in any situation where high reliability and high volume PCBS are needed.
