3 PRINCIPLE OF THE METHOD

After the copper wire soldered to the ceramic substrate layer printed graphics cooked noble metal slurry on the copper surface perpendicular to the substrate is bent 90 °, placed The average of the tensile testing machine at a constant speed from the substrate evenly pull off the lead, with the lead when the pull-off force to represent the attached slurry Focus.

4 Materials

4.1 Al2O3 purity of not less than 95% of the ceramic substrate, the surface roughness in the range of 0.5μm ~ 1.5μm (measured at a distance of 10mm Under the conditions of measurement). 4.2 HLSn63PbA or HLSn63PbB Xiqianhanliao; HLSn63PbAgA HLSn63PbAgB or tin-lead-silver solder; SnAg3.0Cu0.5 Lead-free solder. 4.3 tinned copper wire having a diameter of 0.8mm ± 0.02mm. 4.4 capacity not less than 150mL solder bath. 4.5 Flux. rosin alcohol solution, the concentration of 0.15g/mL ~ 20g/mL.

5 instruments and equipment

5.1 tensile testing machine. range is 0N ~ 100N, accurate measurement and recording of the pulling force should reach ± \u200b\u200b5%. 5.2 screen printing machine, the screen pore size of 74μm. 5.3 tunnel sintering furnace, the maximum temperature of 1000 ℃, temperature control accuracy of ± 10 ℃. 5.4 Thickness. accuracy of 1μm.

6 measuring step

At a temperature of 15 ℃ ~ 35 ℃, relative humidity of 45% to 75%, measured at atmospheric pressure 86kPa ~ 106kPa conditions. 6.1 Preparation of slurry film 6.1.1 The submission slurry Stir in central ceramic substrate printed 2mm × 2mm graphics, graphics should look uniform. each The total number of copies printed sample of not less than 10. 6.1.2 The printed pattern is a ceramic substrate at 150 ℃ ~ 200 ℃ drying, depending on the sintering temperature firing slurry deposition. ......
