Touch up temperature setup:390±10℃, time:1~3S and it’s difficult to control solder time accurately by manual.2. Solder ball and flux need to be cleaned up.3. Manual solder will burn the solder jigs every now and then for different iron operating.Characteristic Introduce the auto soldering machine Equipment：Auto Soldering MachineManufacturer： QUICK1. Precise solder wire speed control system assure the solder quantity consistent.2. Precise temperature control system. 3. Accurate three axis move control.4. The soldering quality is auto control, so it’s better and stable.X axisY axisZ axisTemperature control systemSolder wire speed control systemExcellency Auto soldering processAuto soldering process Glue and place cap.Add silicon then place capacitance following the fixed jig and make sure the pin at the PAD’s centerAuto soldering(some soldering parameters must been set up OK by technician)Auto solderingDo visual check for the soldering qualityVisual Check Auto soldering process introduceStep 1: Manual place cap.Placed the capacitanceAdd silicon then use the jig to fix the PCBA and place capacitanceFix the PCBA and jig to the auto soldering machine Auto soldering process introduceStep 2: Auto solderingPlace the PCBA to auto soldering fixture, press the “STAR” button then start auto soldering following the programme Soldering pin one by oneSolder iron Pipe solder wire Temperature control systemSuction vents of solderSolder quantitycontrol systemSoldering setup:Solder temperature: 400℃Solder time: 2.5S / PADSolder wire speed: 20mm / S Step 3:visual checkAuto soldering process introduceVisual Inspect and Clean up
