Does your new machine require the use of pallets? Some do not. If so, consider these suppliers to help with your pallet: * Asahitec stencils pvt ltd [http://www.smtnet.com/company/index.cfm?fuseaction=view_company&company_id=52967] * Stentech [http

Q1. If I go to the Pb-free solder paste, is it necessary that I have to change my reflow oven OR just by changing with respect to solder paste specification, I can reach my goal? A1. It depends on your current oven. Some ovens can meet the higher t

We have an ongoing problem with our QFP144 packages soldering. It has not received much attention until late due to some customer failures. Most of the failures would show up in ESS testing and be repaired. The failure rate is about 2 in 1000 parts f

Deon, my first response is YES - big time. You are correct that there are some massive issues here. For one thing, lead free solders are only one solution, as conductive epoxy has also been put forward. This was demonstrated on the TAC line at Ne

Depending on your requirements, you could range from a hair dryer, heat gun, toaster oven, hot plate, on up to digitally controlled surfaces and convective systems. You'll have to gauge for yourself whether you are just trying to add some heat energy

Rules of thumb :- 1. Never over flux - not necessary and waste's money. Never top flux neither 2. Top Board temp. around 70C - 105C or there about's pending what laminate you use. Obviously the more flux you apply the higher heat required/denser PC

My first concern would be the choice of solder paste you have. There are better chemistries out there that far exceed the capabilities of the 609 2. Yes, the part will partially float on the solder (assuming plastic qfp). Cross sectioning would sho

| Are there many of you who are soldering through hole parts in your surface mount reflow oven? How repeatable is the process? Do you need to touch up a lot after reflow? We don't do long runs maybe 200, 300 boards max. Can you just screen print

I think the asahi solder is coming out with their own irons if they get enough interest on this forum.

.....and it'll probably be the best soldering iron in the world.
