PCBA reflux tembiricha precautions

Reflow tembiricha inoreva maitiro ekudziya nzvimbo ye soldering kune imwe tembiricha kunyungudutsa solder paste uye kubatanidza zvikamu nemapadhi pamwe chete panguva yakadhindwa dunhu.board assemblyprocess.

Izvi zvinotevera zvinofungwa nezve reflow tembiricha:

PCBA reflux tembiricha precautions1

Kusarudza tembiricha:Kusarudza tembiricha yakakodzera yekuyerera kwakakosha.Tembiricha yakanyanya kukonzeresa kukuvara kwechimwe chinhu, uye tembiricha yakadzikira inogona kukonzera kunyungudika.Sarudza yakakodzera reflow tembiricha zvichienderana nechikamu uye solder paste zvakatemwa uye zvinodiwa.

Heating Uniformity:Munguva yekuyererazve, kuve nechokwadi chekuti kugovera kwekudziya kwakakosha.Shandisa yakakodzera tembiricha mbiri kuti uve nechokwadi chekuti tembiricha munzvimbo yewelding inowedzera zvakaenzana uye kudzivirira yakawandisa tembiricha gradients.

Tembiricha yekubata nguva:Iyo tembiricha yereflow inobata nguva inofanirwa kusangana nezvakatsanangurwa zve solder paste uye soldered components.Kana nguva yacho ipfupi, solder paste inogona kunge isina kunyungudutswa zvachose uye welding inogona kunge isina kusimba;kana nguva yacho yakarebesa, chikamu chacho chinogona kunge chakanyanyisa, chakakuvadzwa kana kutokundikana.

Kukwira kwematembiricha:Munguva yekudzorerazve, kukwira kwekushisa kunokosha zvakare.Kunyanya kukurumidza kukurumidza kusimuka kunogona kukonzera kusiyana kwekushisa pakati pe pad uye chikamu kuti chive chakakura zvakanyanya, zvichikanganisa kunaka kwewelding;Kunyanya kunonoka kusimuka kunozorebesa kutenderera kwekugadzira.

Sarudzo yesolder paste:Kusarudza yakakodzera solder paste zvakare imwe yezvekutenderera tembiricha kufunga.Different solder pastes ane akasiyana melting points uye fluidity.Sarudza iyo yakakodzera solder paste zvinoenderana nezvikamu uye welding zvinodiwa kuti uve nechokwadi chewelding mhando.

Welding zvinhu zvinorambidzwa:Zvimwe zvinhu (senge tembiricha-sensitive components, photoelectric components, etc.) zvinonyanya kutarisisa tembiricha uye zvinoda kurapwa kwakakosha.Munguva yekuyerera tembiricha maitiro, nzwisisa uye namatira kune inomisikidza solder yezvakabatanidzwa zvikamu.
