Hi, all,
My fave Shenzhen PCB vendor, PCBway, is being a bit difficult, and I'm trying to figure out how to respond.
I've designed an adjustable APD power supply for a customer, and am trying to preserve the creepage and clearance requirements despite using small SMT parts, so I need to be able to sneak an L-shaped slot between the pins of a SOT-89 FET (a 500V LND150).
Problem is, their minimum slot width is 0.8 mm (about 31.5 mils), which is wider than the space between the pads.
I can probably sacrifice the middle lead and just use the power pad, but it's unaesthetic to have the lead hovering over a slot.
Anybody got a low-cost PCB vendor that can do narrower slots? 0.3 mm would be great.
Thanks
Phil Hobbs
