Surface Mount Technology (SMT): Theknoloji ea ho sebetsana le liboto tse se nang letho tsa PCB le ho kenya lisebelisoa tsa elektroniki ho boto ea PCB.Ena ke thekenoloji e tsebahalang ka ho fetesisa ea elektronike matsatsing ana e nang le likarolo tsa elektroniki e ntse e fokola 'me ke mokhoa oa ho nka sebaka sa theknoloji ea plug-in ea DIP butle-butle.Litheknoloji ka bobeli li ka sebelisoa ka boto e le 'ngoe, ka theknoloji ea thru-hole e sebelisetsoang likarolo tse sa lokelang ho kenngoa holim'a metsi joalo ka li-transformer tse kholo le li-semiconductors tsa motlakase tse tekiloeng ke mocheso.

Karolo ea SMT hangata e nyane ho feta karolo ea eona ea thru-hole hobane e na le li-lead tse nyane kapa ha e na tse hohang ho hang.E ka 'na ea e-ba le li-pin kapa li-lead tsa mefuta e sa tšoaneng, likhokahano tse bataletseng, matrix a libolo tsa solder (BGAs), kapa ho felisoa 'meleng oa motsoako.

Likarolo tse khethehileng:

> Mochini oa ho khetha ka lebelo le phahameng o hlophiselitsoe likopano tsohle tse nyane, tse mahareng ho isa ho tse kholo tsa SMT (SMTA).

> Tlhahlobo ea X-ray bakeng sa Kopano ea SMT ea boleng bo holimo (SMTA)

>Mohala oa kopano o beha ho nepahala +/- 0.03 mm

>Tšoara liphanele tse kholo tse fihlang ho 774 (L) x 710 (W) ka boholo

> Tšoara likarolo tsa boholo ho 74 x 74, Bophahamo ho fihla ho 38.1 mm ka boholo

> Mochini oa ho khetha oa PQF le ho beha sebaka o re fa maemo a eketsehileng bakeng sa ho matha hanyane le ho aha boto ea mohlala.

> Likopano tsohle tsa PCB (PCBA) li lateloa ke maemo a IPC 610 class II.

>Surface Mount Technology (SMT) mochini o khethang le ho beha sebaka o re fa bokhoni ba ho sebetsa ho sephutheloana sa karolo ea Surface Mount Technology (SMT) e nyane ho feta 01 005 e boholo ba 1/4 ea karolo ea 0201.
