Hi, I think I am becoming good at making holes even for vias and of
course for through-hole components. I can make tiny holes, the results
are very satisfactory, but part of the procedure is complicated.
First of all, I bought these:
http://www.harborfreight.com/20-piece-solid-carbide-micro-bit-grab-bag-44924.htmlbut they looked so fragile, I do not have a press, just a regular
dremel. So I returned them and bought:
http://www.harborfreight.com/30-piece-hss-mini-drill-set-94606.htmlfor 4 dollars, 30 bits that work fairly well!!!
The only problem is that the dremel can only take rather big bits. For
this reason I roll some tape around the bit up until the diameter is
compatible with the dremel collet, and then I drill. Sometimes I can
only make one hole, other times I can make 20 but eventually the bit
will "slide in" and I have to remove it, replace the tape and start
again. This takes a lot of time.
Suggestions?
bye
