Subject: [TN] Bow and Twist Measrement

Hello All,

 

IPC-A-610 Rev. D, Section 10.2.7 allows 1.5% and 0.75% Bow and Twist for
Through-hole and surface mount assemblies accordingly. What percentage
should I be applying if the assembly has mixture of surface mount and
through-hole components?

 

Thank you in advance,

Paymon Sani
