Frequently Asked Questions
Question 1
DIP packages can be assembled onto a PCB through either wave soldering or through socketing. When should I use a
socket?
Answer 1
Benefits of using a socket include: component test, upgrade and exchange, flexibility in IC design, assembly and cost
savings.
Question 2
What’s the difference between stamped contact and machined contact?
Answer 2
Stamping and machining are types of connector manufacturing technologies. TE has developed and produced DIP
socket contacts using stamping technology as an alternative to traditional screw machined contacts, which is an
economical option.
Question 3
What does “300 CL/600 CL, LDR, OTC” mean in the description of DIP sockets with dual leaf contacts?
Answer 3
300 CL means the centerline of the product is 0.3in (7.62mm). So, 600 CL means the centerline is 0.6in (15.24mm).
LDR means that the frame is ladder style and OTC means the frame is over-the-component style.
