It depends on your shop, your processes, the size of your shop, and the vol- ume of the stuff you're doing. Johnson: What seems to be emerging is increased activity with the IPC J-standard; the shis in how you approach ROSE testing, in addition to the customer-driven and OEM- driven demands that are changing for testing inspection regarding finished product. is is especially true for military and medical, which are starting to demand them. Capers: Yes. ose are the top ones. Johnson: As you move toward automation, isn't there an increased need for test and inspection as a part of process control? Capers: Yes.
