2.Managing sensitivity - Vunerable to contaminants or breakage from managing.
3.Wire bondable - With the capacity of developing good wire certain connections.
4.Tight pitch - Could be used for limited pitch components, such as ball grid arrays (BGAs).
5.Contact utilization - Cen the contact be utilized for contacts.
6.Shelf life - Has good shelf life, can be stored for half a year are more.
7.Additional expense - Typically provides cost to your PCB production.
Now, with a couple of comparison qualities, we can better strategy the question which kind of PCB complete to use.
