Measure Solder Coatings on PCBs

Because EU directives like EU2002/95/EC and EU2002/96/EC prohibit lead and other heavy metals, the solderable coating systems used on printed circuit boards must now be lead free. However, immersion tin…

Measure Copper Thickness in PCB Through-Holes

  • Post Author:

As electronic devices get smaller and smaller, conducting paths must be positioned even more closely together on printed circuit boards (PCBs). This is why, today, most PCBs are multi-layered. In…

Thickness Measurement of Conformal Coatings on Printed Circuit Boards

  • Post Author:

Conformal coating material is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes. Coatings on assemblies which are too thin or totally uncoated and therefore non-protected…

Determine Lead Content In Solder Alloys

  • Post Author:

For most electronics applications it is prohibited to use solders that contain lead (RoHS and WEEE directives). However, the so-called tin whiskers that sometimes grow from the surface of unleaded…
