FAQ
PCB cleaning after solderingWhy clean the print circuit boards after soldering?- It ensures that the resulting product has a far longer lifespan and is reliable for longer.
Trends that raise demands on cleanliness in the pick-and-place process- The general miniaturisation of PCB
- The reduction of operating voltage
- Narrower and smaller component spacing
- Shorter distances between conducting paths
- The rise in the use of electronics in all areas of industry
What are the most common problems? - Corrosion causing leakage current and short circuits
- Dendrite formation causing leakage current and short circuits
What causes these problems?Stencils, misprints and squeegees cleaningWhy to clean stencils, squeegees and misprints of PCB?- 51 – 72 % of the errors caused by soldering happen as the result of poor solder paste printing.
What are the most common problems?- Not enough paste is applied
- Solder joint connection
- Creation of "Solder ball"
What causes these problems?- The residue of old solder paste remaining on the template
Conformal Coating cleaning from coating: pcns, frames and machine partsWhy to remove coating PCB and parts of coating devices?- Coating PCBs: enables the removal of defective components from PCB, re-soldering and coating
- Coating frames and parts for coating devices: Makes sure of fully-functioning coating frames and coating technology
What are the most common problems?- PCBs: failure of components on PCB during the lifespan of a product
- Dendrite formation and corrosion beneath the coating and resulting leakage current and short circuits
- Coating frames and parts of coating devices: Layers of hardened coating blocking coating device frames and parts so that the coating process is not 100 % possible.
Cleaning of filters of reflow ovens and waves, soldering frames cleaningWhy to clean filters, coolers and soldering frames?- To ensure a stability of the soldering profile and extend the life of parts
What are the most common problems?- Filters and parts of soldering technology: incorrect functioning of filters, coolers, and other parts, affecting of circulation of air and setting of solder profile
- Soldering frames: incorrect position of PCB in the frame, no functions of clamps and fixation springs
What causes these problems?- Flux and other residue from the soldering process
