Why aren’t components in DIP package shipped with straight pins?

I've noticed that all DIP packaged devices have pins which are at an angle other than 90∘ and need to be bent so that the angle is right for insertion into holes on the PCB or wherever. Is there any reason other than tradition for that?

I’m pretty sure that auto-insertion machines expect to set pins to the desired orientation by pushing in on them from the outside.

If the part is gripped from the outside and squeezed just far enough for the pins to enter the holes, while the part is being squeezed, the elasticity of the pins will usually cause it to “grip” the holes as soon as they’re released. Such gripping behavior may help keep the parts from being dislodged before wave soldering is complete.

How do I solder loose wires to a flexible PCB?

Try to repair electronic sphygmomanometer now. It seems wires fell off from the flexible PCB, leaving trail on there. How do I solder them to the flex-PCB?

What are the black spots in lead-free solder joints on PCB?

I am prototyping a PCB, using Chip Quik’s “SMDSWLF.031, a Sn96.5/ Ag3.0/ Cu0.5 solder with 2.2% no-clean flux. I find that the black spots appears frequently in larger pads on my board. I wonder if it is because I left the soldering iron more time heating the solder and that burnt the flux. What is that black residue? Is that a sign of a bad joint or maybe bad soldering technique?
