Hi Arturo,
Capacitors are more fragile than resistors or other components. The cracking,
if not present before soldering, typically occurs as the result of too rapid
cooling from reflow in combination with large fillets (thermal shock).
Solution options include: less aggressive cooling and smaller soldering pads
to make fillets smaller.
