Maemong a mangata, ntho e kholo ka ho fetisisa e amang nako ea bophelo eatšepe e sollangntlha ke mocheso oa soldering.
Pele ho ts'ebetsong e hlophisitsoeng ea melao ea RoHS (lithibelo holim'a lintho tse kotsi) ka la 1 July, 2006, lead in solder wire e lumelloa.Ka mor'a moo, tšebeliso ea loto (le lintho tse amanang le eona) e thibetsoe ntle le lisebelisoa le mekhoa e latelang: lisebelisoa tsa bongaka, lisebelisoa tsa ho hlahloba le ho lemoha, lisebelisoa tsa ho lekanya le lisebelisoa haholo-holo libakeng tsa sesole le tsa sefofane ho kenyeletsa li-sensor tsa likoloi (litsamaiso tsa ho laola likoloi le lihlahisoa tsa airbag). ), indasteri ea lipalangoang tsa literene, joalo-joalo.
Mohala o tsebahalang haholo oa lead alloy tin o tšoauoa ka ntlha e qhibilihang e ka bang likhato tse 180.Sebaka se qhibilihang sa terata e tloaelehileng e se nang loto e ka bang likhato tse 220.Phapang ea mocheso oa likhato tse 40 e bolela hore e le hore u phethe se khotsofatsangsolderkopanetsweng ka nako e tšoanang, re lokela ho eketsa mocheso oa seteishene solder (haeba soldering nako e eketseha, ho bonolo ho senya likarolo le PCB boto).Ho eketseha ha mocheso ho tla fokotsa bophelo ba ts'ebeletso ea ntlha ea tšepe ea soldering le ho eketsa ts'ebetso ea oxidation.
Setšoantšo se latelang se bontša phello ea ho eketseha ha mocheso bophelong ba tšebeletso ea tšepe ea soldering ntlha.Ho nka likhato tse 350 e le boleng ba litšupiso, ha mocheso o eketseha ho tloha ho likhato tse 50 ho isa ho tse 400, bophelo ba tšebeletso ea ntlha ea tšepe ea soldering bo tla fokotseha ka halofo.Ho eketsa mocheso oa tšebeletso oa ntlha ea tšepe ea soldering ho bolela hore bophelo ba tšebeletso ea tšepe ea tšepe bo fokotsehile.
Ka kakaretso, mocheso oa solderng oa motsoako oa solder o se nang lead o khothaletsoa ho ba 350 ℃.Leha ho le joalo, mohlala, hobane boholo ba sesebelisoa sa 01005 se nyane haholo, re khothaletsa ts'ebetso ea 300-degree soldering.
Bohlokoa ba ho nepahala
U lokela ho hlahloba mocheso o sebetsang oa seteishene sa soldering kamehla, se ke keng sa eketsa bophelo ba ts'ebeletso ea tšepe ea tšepe, empa hape le ho qoba mocheso o feteletseng kapa mocheso o tlaase oa soldering ha lihlahisoa tsa soldering.
Ka bobeli li ka baka mathata nakong ea solder:
·Mocheso o feteletseng: basebetsi ba bangata ba koetlisitsoeng ba tla nahana hore hoa hlokahala ho eketsa mocheso oa soldering ho lokisa bothata ha ba fumana hore solder ha e khone ho qhibiliha kapele.Leha ho le joalo, ho eketsa mocheso ho tla etsa hore mocheso sebakeng sa ho futhumatsa o be holimo haholo, e leng se tla lebisa ho warping ea pad, mocheso o feteletseng oa solder, ho senya substrate le manonyeletso a solder ka boleng bo bobe le ho feta.Ka nako e ts'oanang, e tla eketsa oxidation ea ntlha ea tšepe ea soldering le ho baka tšenyo ho ntlha ea tšepe ea soldering.
Mocheso o tlase haholo oa solder o ka lebisa nako e telele haholo ea ho lula sebakeng sa soldering le ho fetisa mocheso le ho feta.Sena se tla ama bokhoni ba tlhahiso le boleng ba manonyeletso a batang a solder.
Ka hona, tekanyo e nepahetseng ea mocheso ke ea bohlokoa ho fumana mocheso oa ho lokisa oa soldering.
