Is teicneolaíocht nua modhnaithe dromchla é cumhdach léasair, ar a dtugtar cumhdach léasair nó leá léasair freisin. Cruthaíonn sé ciseal cumhdaigh filler atá nasctha go miotalóireachta leis an dromchla foshraithe trí ábhar cumhdaigh a chur leis an dromchla foshraithe agus léas léasair dlúis ardfhuinnimh a úsáid chun é a chlaochlú mar aon le ciseal tanaí ar dhromchla an tsubstráit.
Faoi láthair, is spraeáil teirmeach nó ábhair spraeála teirmeacha iad na hábhair a úsáidtear go coitianta le haghaidh cumhdach léasair, lena n-áirítear ábhair chóimhiotail féin-intuaslagtha, ábhair scaipthe cairbíde nó ábhair ilchodacha, agus ábhair cheirmeacha.
Leis aibíocht mhéadaitheach na teicneolaíochta léasair agus cur i bhfeidhm forleathan léasair ardchumhachta, cuireadh an próiseas cumhdaigh léasair chun cinn de réir a chéile agus cuireadh i bhfeidhm é mar gheall ar a bhuntáistí amhail dífhoirmiúchán beag oibre, ráta caolaithe íseal, liúntas próiseála beagáinín beag, struchtúr dlúth, agus ráthaíocht éifeachtach ar fheidhmíocht alloy. Mar sin féin, is dóchúil go gcuirfidh cumhdach léasair scoilteadh struis mar gheall ar ionchur teasa tiubhaithe. Bunaithe ar thuiscint ar thréithe na teicneolaíochta cumhdaigh léasair, tá sraith púdair cumhdaigh léasair forbartha againn, agus aithníodh feidhmíocht agus feidhmíocht an phróisis táirge d'aon toil ag custaiméirí. $ $
