Q: What is the cost for shipping and handling?

A: U.S. Mail shipping rates are the "Commercial Base" discounted prices set by the United States Postal Service and are subject to change. Priority Mail rates are based on small flat rate box prices. Current rates are:

  • USA First Class Mail - $2.54
  • USA Priority Mail (2-3 day delivery) - $6.10
  • UPS or Federal Express calculated at check out for USA addresses.
  • Canada First Class Mail - $9.03
  • Canada Priority Mail - $23.70
  • International First Class Mail- $12.89
  • International Priority Mail (6-10 day delivery) - $32.25

First class mail reaches most locations in the U.S. within two days and worldwide within 10 business days.

We can also ship to most foreign countries via UPS, Federal Express, DHL, and TNT. Contact us for a quotation or with your account number if you wish to ship with one of these carriers.

Q: Can you provide a tracking number for my shipment?

A: Tracking numbers are provided to you in an email confirming shipment when we have shipped your order. International mail shipments will be provided with a CN22 customs number. Some foreign countries' postal services use this number to track shipments all the way to the destination.

Q: Can you ship using my UPS, FedEx, DHL or TNT account?

A:  Yes. You can include your account number and the associated postal code along with your desired shipping service in a customer note on the online order form or send them to us in an email.


Q: Are the op-amp ICs you sell genuine factory components?

A:  Yes. All of our third-party components are sourced from authorized U.S. distributors including Mouser, Digi-Key and Newark Element14.


Q:  I've never soldered surface mount parts before; is it difficult?

A:  Soldering SMT parts is no more difficult than through-hole parts if you have the right tools. I use a conical 1/64" tip which allows me to solder 0.5mm pin pitch parts without any problem; compared to that, standard SO8 (1.27mm pin pitch) parts are a piece of cake. Probably the most important thing is to liberally apply solder flux to the pads before you put the part down. I like to use felt-tipped flux pins (they look just like marker pins and you can get them from DigiKey or Mouser).

Do the following:

1.  Apply solder flux to the pads.
2.  Position the part on the pads.
3.  Touch the iron to one of the end pads; allow enough time for the pad and component to absorb sufficient heat and then feed in some solder using your other hand. If the positioning of the part looks OK, then use the same procedure to tack down the opposite corner.
4.  Solder the remaining pins with a small amount of additional solder.
5.  Use solder wick to clear any solder bridges that might occur between pins. This doesn't happen very often on SOIC parts unless you get too carried away with the solder; this is more likely to occur on finer pitch parts.

Here are some good Dave Jones YouTube videos on soldering.

In part 1, he talks about tools:

In Part 2, he does through-hole soldering:

In Part 3, he shows how to do surface mount soldering. At 9:10 he shows how to solder an SO8 IC.

Also, Warren Young at Tangentsoft has produced a series of very good tutorial videos addressing through-hole and SMT soldering techniques. You can view them here (requires Ver. 8 Flash (or later) plugin for your browser).
