Ngaba ukhe wacinga ukuba ibhodi yakho yesekethe ye-elektroniki idityaniswe njani?Kwaye zeziphi iindlela ezisetyenziswa ikakhulu kwindibano PCB?Apha, uya kufunda ngakumbi malunga nendlela yokuhlanganisa kwindibano yePCB.
Inkcazo ye-SMT
I-SMT (i-Surface Mount Technology) lolunye uhlobo lwendlela yokudibanisa ibhodi yePCB, indlela yokuvelisa iisekethe zombane, apho amanye amacandelo athi axhonywe khona.Ibizwa ngokuba yi-SMT(Surface Mount Technology).Ithathe indawo yetekhnoloji yomngxunya ngokufanelekileyo apho amalungu adityaniselwe enye kwenye ngeengcingo ezidlula kwimingxuma egqojoziweyo.
Phantse zonke iihardware zombane eziveliswayo namhlanje zenziwe kusetyenziswa itekhnoloji ye-surface Mount, i-SMT.Izixhobo ezihambelana nomphezulu wokunyuka, ii-SMD zibonelela ngeenzuzo ezininzi ngaphezu kwabaphambili bazo abakhokelayo ngokwemigaqo yokwenziwa kunye nokusebenza rhoqo.
Umahluko phakathi kwe-SMT kunye neTHT
Kuhlala kukho iindidi ezimbini zendlela yokuhlanganisa iPCB, iSMT kunye neTHT
Icandelo le-SMT lidla ngokuba lincinci ngokobukhulu kunobuchwephesha bomngxuma wokutyhutyha kuba alinawo umkhondo wokuthatha sonke isithuba esikhululekileyo.Nangona kunjalo, inezikhonkwane ezincinci zeendlela ezahlukeneyo, i-matrix yeebhola ze-solder, kunye noqhagamshelwano olucaba apho umzimba wecandelo uphela ukuze ubambe ngokuqinileyo.
Kutheni i-SMT isetyenziswa ngokubanzi?
Ubuninzi obuveliswe iibhodi zeesekethe zombane kufuneka zenziwe ngendlela enomatshini kakhulu ukuqinisekisa elona xabiso liphantsi lokwenziwa.Amacandelo e-elektroniki akhokelayo awaziboleki kule ndlela.Nangona ubuxhakaxhaka obuthile bebunokwenzeka, icandelo elikhokelayo kwakufuneka libunjwe kwangaphambili.Kwakhona xa izikhokelo zifakwe kwiibhodi ngokuzenzekelayo iingxaki bezisoloko zidibana njengoko iingcingo bezisoloko zingangeni ngokufanelekileyo amaxabiso emveliso acothayo kakhulu.
I-SMT isetyenziswa phantse ngokukodwa ekwenzeni iibhodi zeesekethe zombane kule mihla.Zincinci, zihlala zibonelela ngenqanaba elingcono lokusebenza kwaye zingasetyenziswa kunye ne-automated pick kunye nomatshini wendawo othi kwiimeko ezininzi zonke bit ziphelise imfuno yokungenelela ngesandla kwinkqubo yokuhlanganisa.
I-PHILIFAST izinikele kwindibano ye-SMT kunye ne-THT iminyaka engaphezu kweshumi, banamaqela amaninzi eenjineli kunye nomsebenzi ozinikeleyo.Konke ukubhideka kwakho kuya kusonjululwa kakuhle kwi-PHILIFAST.
