Yes!!! How can we assemble boards with 20 pitch when we allow 0.008� error to the master art? Excellent question!!! IPC-D-300G has nothing to do with assembler requirements. It is written by and for fabricators, so that they can be comfortable.

Hi Yngwie Have you got a reflow oven yet. If not, forget about complicated profiling with test runs or reflow trackers. We've got a nice oven with integrated temperature-feedback system. You build any profile you want and the oven will adjust its hea

There are instruments from ECD, KIC and Datapaq that are used in addition to classic profiling for oven thermal management and they also have some very efficient prediction software for profiling. I am not an advocate of common profiles. Most boards

Hello, On customer want to make a aluminium board. It will have SMD Led on it. Like I never "played" with this before can someone tell me what I know to know on that new thing. What kind of reflow profile we need. What just I be aware of, is

yngwie, are you getting a wave from the customer to say it's not your fault you fried the parts? Profiling's one of those things that is a pain to dobut it's one of the most important factors in the assembly processes. I've read and seen instances w

One more thing I want to add. Don't turn this into some big deal. Its not atom splitting, or black majic.Bottom line is that you are going to be doing some experiments to prove it to yourself and whomever else requires the data. Profiling is time con

What is your process? Wave solder, hand solder, pin in paste?

We had the exact same problem in early stages of lead-free. Very random positions of defect + some boards were 100% O.K. and others were an explosion of what I see in your picture. Turned out to be bad processing/materials from board house. I'm do

Hi, how to ensure flexible boards do not warp after reflow and still remain flat for subsequent operations. What is the best way to hold and transport these strips from one process to another. Thanks!
