Reflow soldering principle
The reflow oven is used to solder the SMT chip components to the circuit board in the SMT process soldering production equipment. The reflow oven relies on the hot air flow in the furnace to brush the solder paste on the solder joints of the solder paste circuit b...Read more -
WAVE SOLDERING DEFECTS
Incomplete Joints on a Printed Circuit Board-WAVE SOLDERING DEFECTS The incomplete solder fillet is often seen on single-sided boards after wave soldering. In Figure 1, the lead-to-hole ratio is excessive, which has made soldering difficult. There is also evidence of resin smear on the edg...Read more -

PCB Rework Tips in the end of SMT PCBA
PCB Rework After the PCBA inspection is completed, the defective PCBA needs to be repaired. The company has two methods for repairing the SMT PCBA. One is to use a constant temperature soldering iron (manual welding) for repair, and the other is to use a repair workben...Read more -
How to use solder paste in PCBA process?
How to use solder paste in PCBA process? (1) Simple method for judging the viscosity of solder paste: Stir the solder paste with a spatula for about 2-5 minutes, pick up a little solder paste with the spatula, and let the solder paste fall down naturally. The viscosity is moderate; if the solder...Read more -

Defect Of Blow Holes On The PCB
Pin Holes & Blow Holes on a Printed Circuit Board Pin holes or blow holes are the same thing and caused by the printed board outgassing during soldering. Pin and blow hole formation during wave soldering is normally always associated with thickness of copper plating. Moisture in the board e...Read more -
What is wave soldering?
What is wave soldering? Wave soldering is a large-scale soldering process by which electronic components are soldered to a printed circuit board (PCB) to form an electronic assembly. The name is derived from the use of waves of molten solder to attach metal components to the PCB. The process use...Read more -
