Siyintoni isizathu sokuthengiswa kwamaza ngetoti?Uyintoni umphumo?Indlela yokulungelelanisa?

Abahlobo abaninzi be-wave soldering baneemeko ezidityaniswe nge-tin xa usebenzisa i-wave soldering, eyinkathazo kakhulu.Ezona zizathu zale meko zezi zilandelayo:

Umsebenzi we-Flux awanele.

I-Flux ayimanzi ngokwaneleyo.

Umyinge we-flux ofakiweyo uncinci kakhulu.

Ukusetyenziswa kwe-flux engalinganiyo.

Indawo yebhodi yesekethe ayinakugqithwa nge-flux.

Akukho toti kwindawo yebhodi yesekethe.

Ezinye iipads okanye iinyawo ze-solder zixutywe kakhulu.

I-wiring yebhodi yesekethe ayinangqiqo (ukusasazwa okungenangqiqo kwamacandelo).

Icala lokuhamba alilunganga.

Umxholo we-tin awanele, okanye ubhedu lugqithise umgangatho;[ukungcola okugqithisileyo kubangela ukuba indawo yokunyibilika (i-liquidus) yolwelo lwe-tin iphakame] ityhubhu enogwebu ivaliwe, kwaye i-foaming ayilingani, okubangela ukugquma okungalinganiyo kwe-flux kwibhodi yesekethe.

Ukumiswa kwemela yomoya akunangqiqo (i-flux ayivuthelwanga ngokulinganayo).

Isantya sebhodi kunye nokufudumala kwangaphambili akuhambelani kakuhle.

Indlela yokusebenza engafanelekanga xa udipha inkonkxa ngesandla.

Ukuthambekela kwekhonkco akunangqiqo.

I-crest ayilingani.

Ekubeni ukudibanisa i-tin kuya kubangela isiphaluka esifutshane se-pcb, kufuneka silungiswe ngaphambi kokuba siqhubeke sisetyenziswa.Indlela yokulungisa ukukhomba i-flux encinci (oko kukuthi, i-solvent yeoli ye-rosin), kwaye emva koko usebenzise i-ferrochrome yobushushu obuphezulu ukutshisa indawo ye-tin yokudibanisa ukuyinyibilikisa, kunye nendawo ye-tin yokudibanisa Ngaphantsi kwesenzo soxinzelelo lomphezulu. , iya kurhoxa kwaye ayisekho isiphaluka esifutshane.

Izisombululo

1. I-flux ayanele okanye ayifani ngokwaneleyo, yandisa ukuhamba.

2. I-Lianxi ikhawuleza isantya kwaye ikhulise i-angle yengoma.

3. Ungasebenzisi i-wave e-1, sebenzisa amaza ama-2 e-wave enye, ukuphakama kwe-tin akufuneki kube yi-1/2, kwanele ukuba uchukumise nje phantsi kwebhodi.Ukuba unetreyi, icala letoti kufuneka libe kwelona cala liphezulu lomngxuma wetreyi.

4. Ngaba ibhodi ikhubazekile?

5. Ukuba i-2-wave shot enye ayilungile, sebenzisa i-1 wave ukubethelela, kwaye i-2-wave ibetha ezantsi ngokwaneleyo ukuba ichukumise isikhonkwane, ukuze imilo ye-solder joint ilungiswe, kwaye kuya kuba kuhle xa. iyaphuma.

Ngezi zizathu zingasentla, unokujonga kwakhona ukuba ngaba umatshini wokuthengisa amaza unazo ezi ngxaki zilandelayo:

1. Umgama owuncopho wobude.

2. Ingaba isantya setsheyini sifanelekile.

3. Ubushushu.

4. Ingaba isixa setoti kwisithando somlilo sanele.

5 Ngaba ingca yomaza iphuma enkonkxeni?
