Important Notice: 3M PLCC products have tin plating on the contact wiping surface, necessary for mated reliability. Tin whiskers are an inherent characteristic of tin, and mechanical stress can stimulate growth. Users should consider the suitability of PLCC sockets for their specific applications, considering lifespan, environment, mechanical stresses, humidity, and thermal cycling. 3M follows iNEMI plating recommendations for whisker mitigation.
Warranty: Limited to ninety (90) days from purchase for defects in material and manufacture. 3M disclaims other warranties, including implied warranties of merchantability or fitness for a particular purpose. Remedies are limited to replacement, repair, or refund at 3M's option. 3M is not liable for indirect, special, incidental, or consequential damages.
