Ngaba uyazi malunga nokuhanjiswa kwakhona kwe-SMD? Yindlela enika umdla yokulungisa izinto ezincinci kwiiPCBs. Oku kukwasebenzisa kakhulu kwi-Electronics SMD reflow ipholile, kuba ilungile: itshiphu kwaye iyakhawuleza == i-spam ilayisha kakhulu ibhokisi yakho yeposi.
Izinto ezilungileyo malunga ne-SMD Reflow
Kungcono ke ngoko solder ngesandla) Hlaziya kwakhona. Ngale ndlela igcina ilungile zonke iicomps kwaye isebenzise iimpazamo ezincinci. Isivakalisi naso ngoku sifundeka ngokutyibilikayo. Ikwaza nenqaku lobushushu elilawulwa yikhompyuter ukuqinisekisa ukuba iindawo zifumana ukufudumeza okuchanekileyo Oku kuya kuthintela ibhodi ukuba ibe mdaka.
Iingcamango ezintsha ze-SMD kunye namaqhinga, iTekhnoloji yokuReflow
Ukuqhubekeka kwakhona kwe-SMD oku kuhlala kungcono kwaye kungcono ngokuhamba kwexesha. I-solder engenalo i-load isetyenziswa namhlanje, kwaye oku kuyingenelo kwimekobume. Intshontsho elitsha elikwibloko ebizwa ngokuba yi-vapor phase soldering, apho umphunga usetyenziselwa ukuwufudumeza. Oku kuthintela ikhefu elinokuba neendleko ezinkulu ngenxa yokuguquguquka okukhawulezileyo kobushushu.
I-SMD reflow -Ubukhulu becala umatshini wenziwa ngoko kufuneka ukhuseleke (Umthombo womfanekiso: Sparkfun Oku kuvumela iikhomputha ziqinisekise ukuba indawo nganye ishushu kwaye ipholile ngokuchanekileyo. Le teknoloji kufuneka ihlolwe kwaye imithetho isalandelwa.
Zonke ezi zinokujongwa ngokulula ngenye ukuba isebenzile kwi-SMD reflow kuphela owaziyo amanyathelo asisiseko ekufuneka uwalandele. Beka amacandelo kwindawo yawo ukusuka kwibhodi yesekethe kuqala kwaye ubeke i-solder paste kwiindawo apho yayiza kuba khona. Emva koko ubeka ibhodi kwi-oven yokubuyisela kwaye yenza wonke lo msebenzi onzima. Khumbula ukugcina iliso kuyo
Umgangatho kunye neNkonzo kwi-SMD Reflow
Nangona kunjalo, ukuhanjiswa kwakhona kwe-SMD kuyafuneka ukugcina umgangatho womgangatho wokwenziwa kunye nemveliso. Kwakhona, kunciphisa iimpazamo xa izinto ziziswa kwimarike (apho yonke loo mali ihlala khona). Khetha ifemu ebikwishishini lokubonelela ngeenkonzo ezininzi njenge-SMD yokubhaka ukuphucula ukusebenza kwenkqubo. Ngexesha elizayo xa ufuna umnikezeli wenkonzo osebenzayo, i-samd reflow njl LinearLayoutManager.orientation
Ibizwa ngokuba yi-SMD reflow, ethi njengomgaqo osebenzayo osetyenziswa kumacandelo amaninzi afana neemoto, iinqwelomoya, i-electronics kunye nezixhobo zonyango. Ikwasetyenziswa ekwenzeni izixhobo ezifana neeselfowuni, iitafile kunye neelaptops. Oku kukhokelele kwinguqu yesantya sokwenziwa kwenkqubo yokwenziwa kombane kunye nokusebenza kakuhle, ukwenza yonke into ikhawuleze ngemveliso yomgangatho we-100%.
Le yiTekhnoloji yokuReflow ye-SMD kweyona intle kakhulu
Ngaba ukhe weva ngokuqukunjelwa kwakhona kwe-SMD? Le yindlela ekrelekrele yokudibanisa izinto ezincinci ebhodini. Utshintsho lwetekhnoloji lusetyenziswa kakhulu ngaphakathi kwishishini leegajethi zeshishini kwaye lufunyenwe imeko ebaluleke kakhulu ekufaneleyo ukufumana okungaphezulu okuphezulu-okugqwesileyo kunye nendlela yabo eyongezelelweyo yeenzuzo ezongezelelweyo zobunzima be-acosar.
Xa kuthelekiswa nendlela ye-welding yendabuko, itekhnoloji ye-SMD yokubuyisela kwakhona ineenzuzo ezingenakuthelekiswa nanto. Eyokuqala yeyokuba iqhuba ngokugqibeleleyo indawo zonke kwiPCB, enokuba negalelo kwiimpazamo ezincinci. Ayizi kuphela ezi ziya kunciphisa umngcipheko weempazamo zombane kodwa zinyusa ukusebenza ngokubanzi. Ukongeza, ubushushu kunye nolawulo lobushushu ngoku lwenziwa yinkqubo yekhompyuter ukunqanda naziphi na iiPCBs ezonzakeleyo njengoko icandelo ngalinye ngoku lifumana indawo yalo yepunch efunwayo.
