Yes, continue to use SAC solder. However, as far as I know, the problem become more severe when cooling rate is increased.

The design rules for solder thiefs are that the extra pads must be bigger than the proceeding pads to be worth while as a minimum guide the pad is 3x the size of the proceeding pad so if the pad is 0.030" the thief would be 0.090" wide. As steve has

I am four weeks into my new job, there always seems to be some issues here with PCB every week. Today while I was checking some assemblies with micro-scope, I found a lot of tiny bubbles/blisters on the board. They are just little dots if you look

Thank you for your quick responce. First let me say that I have read your articals and found them to be very comprensive and informative. Good Work Patrick My direct expereince with regard to water soluable flux is neglagable at best. In discusion w

Hi Scott, Here is another thought. Check your wave solder machine visually. Does the wave flow on both sides of the nozzle? If not, you may have some dross build-up which may be causing your problem. Generally it will only happen on the very fir

I am looking for some design guidelines (length, width, spacing) for solder thieves which are placed behind trailing pins of wave soldered SOICs. I'd appreciate it if some one could direct me to the appropropriate reference. Also, has any one perform

Given that you are bridging front to back, contast the situation with the thiefs used to prevent bridging when wave soldering SOIC. If this is reasonable, the thiefs should be located behind the trailing connector pins. You can prove-out this [and

Hi, I am currently using a peelable mask prior to wave soldering and have started exploring water soluble/washable masks. The mask will be used with water based and alcohol based flux. Are there any compatability issues to concider and how will this

Hi John, can�t find that one in the archives. Isn�t all the trouble you may get dependend on the way you design the thing? For example, tight fit with with step/ridge nearly zero and clamps for holding down the inner circle to prevent vibrations. F
