Dear all, I want to know the difference between the CSP and the BGA (I think there is only in the mesh pin difference). Secondly, if their solder balls have same dia, LxBxH are also same with the the manufacturing of the pin coating chemical elemen

Sure you can use it it with leaded HASL. Recognize that ... * Your Sn42/Bi58 will no linger be Sn42/Bi58 * Your leaded HASL will no longer be the same leaded HASL that walked in the door to your plant * Lead from HASL coatings can diffuse through the

I have a right angle male shrouded connector and the whole set of termination leads is tin lead plated, at least 100 microinches thick. Should the entirety of the lead be conformal coated? Or can we have just the joint coated? I know I have coated le

Especially VCM - volatile condensable materials. Strictly verboten around optics.
