Imbali yokuthengiswa kwamaza

Umenzi we-Wave soldering u-Chengyuan uya kukwazisa ukuba i-wave soldering ikhona amashumi eminyaka, kwaye njengeyona ndlela iphambili ye-soldering components, idlale indima ebalulekileyo ekukhuleni kokusetyenziswa kwe-PCB.

Kukho ukutyhala okukhulu ukwenza i-electronics encinci kwaye isebenze ngakumbi, kwaye i-PCB (intliziyo yezi zixhobo) yenza oku kwenzeke.Lo mkhwa uphinde wavelisa iinkqubo ezintsha zokuthengisela njengenye indlela ye-wave soldering.

Phambi kweWave Soldering: Imbali yeNdibano yePCB

Ukuthengisa njengenkqubo yokudibanisa iinxalenye zentsimbi kucingelwa ukuba kwavela kamsinya nje emva kokufunyanwa kwetoti, eseyona nto iphambili kwii-solders namhlanje.Kwelinye icala, iPCB yokuqala yavela ngenkulungwane yama-20.Umqambi waseJamani u-Albert Hansen weza nombono wenqwelomoya yamanqanaba amaninzi;equka i-insulating layers kunye ne-foil conductors.Uphinde wachaza ukusetyenziswa kwemingxuma kwizixhobo, eyona ndlela ifanayo esetyenziswayo namhlanje ukunyuswa kwenxalenye yomngxuma.

Ngexesha leMfazwe Yehlabathi yesiBini, uphuhliso lwezixhobo zombane neze-elektroniki lwaqalisa njengoko amazwe ayefuna ukuphucula unxibelelwano kunye nokuchaneka okanye ukuchaneka.Umqambi wePCB yanamhlanje, uPaul Eisler, uphuhlise inkqubo ngo-1936 yokudibanisa ifoyile yobhedu kwiglasi yokugquma icwecwe.Kamva wabonisa indlela yokudibanisa unomathotholo kwisixhobo sakhe.Nangona iibhodi zakhe zasebenzisa i-wiring ukudibanisa amacandelo, inkqubo ecothayo, ukuveliswa kwee-PCB ezininzi kwakungadingeki ngelo xesha.

Wave Welding to Rescue

Ngo-1947, i-transistor yaqanjwa nguWilliam Shockley, uJohn Bardeen, kunye noWalter Brattain kwiBell Laboratories eMurray Hill, eNew Jersey.Oku kwakhokelela ekucuthweni kobungakanani bamacandelo e-elektroniki, kunye nophuhliso olulandelayo kwi-etching kunye ne-lamination yavula indlela yobugcisa bokuvelisa imveliso.
Ekubeni amacandelo e-elektroniki asekho emingxunyeni, kulula ukubonelela nge-solder kwibhodi yonke ngaxeshanye, kunokuba uzithengise ngabanye ngentsimbi yokuxubha.Ngaloo ndlela, i-soldering wave yazalwa ngokuqhuba ibhodi yonke phezu "kwamaza" e-solder.

Namhlanje, i-wave soldering yenziwa ngumatshini wokudibanisa amaza.Inkqubo ibandakanya la manyathelo alandelayo:

1. Ukunyibilika - I-solder ifudunyezwa malunga ne-200 ° C ngoko ihamba ngokulula.

2. Ukucoca - Coca icandelo ukuqinisekisa ukuba akukho zithintelo ezithintela i-solder ukuba ibambelele.

3. Ukubekwa - Beka i-PCB ngokufanelekileyo ukuqinisekisa ukuba i-solder ifikelela kuzo zonke iindawo zebhodi.

4. Isicelo - I-Solder isetyenziswe kwibhodi kwaye ivunyelwe ukuba ihambe kuzo zonke iindawo.

Ikamva le-Soldering yamaza

I-Wave soldering yayiyeyona ndlela ixhaphakileyo yokusetyenziswa kwe-soldering.Oku kungenxa yokuba isantya sayo singcono kunesoldering manual, ngaloo ndlela iqonda i-automation yendibano yePCB.Inkqubo ilungile kakhulu ekuthengiseni ngokukhawuleza okukhulu, izithuba ezibekwe kakuhle kumngxuma.Njengoko imfuno yeePCB ezincinci ikhokelela ekusetyenzisweni kweebhodi ezininzi kunye nezixhobo zokubeka umphezulu (SMDs), ubugcisa obuchanekileyo bokuthengisa kufuneka buphuhliswe.

Oku kukhokelela kwindlela ekhethiweyo yokuthengisa apho uqhagamshelo luthengiswa ngokwalo, njengakwi-soldering yesandla.Ukuqhubela phambili kwiirobhothi ezikhawulezayo kwaye zichaneke ngakumbi kune-welding manual zenze ukuba kwenzeke ukuzenzekelayo kwendlela.

I-Wave soldering ihlala iyindlela ephunyezwe kakuhle ngenxa yesantya kunye nokuziqhelanisa neemfuno ezintsha zoyilo lwePCB ezithanda ukusetyenziswa kwe-SMD.Kuye kwavela i-wave soldering ekhethiweyo, esebenzisa i-jetting, evumela ukusetyenziswa kwe-solder ukuba ilawulwe kwaye iqondiswe kuphela kwiindawo ezikhethiweyo.Izinto eziphuma emngxunyeni zisasebenza, kwaye i-wave soldering yeyona ndlela ikhawulezayo yokuthengisa ngokukhawuleza inani elikhulu lamalungu, kwaye inokuba yeyona ndlela ilungileyo, kuxhomekeke kuyilo lwakho.

Nangona usetyenziso lwezinye iindlela zokuthengisa, ezinje ngokukhetha i-soldering, lukhula ngokuthe ngcembe, i-wave soldering iseneenzuzo ezenza kube yinto enokwenzeka kwindibano yePCB.
