Hi everybody, Does someone have experience in the assesment of Surface Mount devices? For the moment we have the Must System II of Multicore but it is not effective to assess the solderability of Surface mount devices. Indeed the conditions are not

I had a 1995 SENSBEY MXL-400J at the last place I worked. I had very good results- easy to setup, run and maintain. It has a paint gun type spray head. Good idea to have spares cause they can clog. I sprayed a Multicore NC flux. Only downer was a fai

I'm having trouble printing leads on a fine pitch part. The lead is only .008". I'm using a DEK 265 with metal squeegee and using WS200 multicore solder paste.The stencil is laser cut and polished. I've experimented with different pressures and diffe

Had exactly the same type of issues. Tried everything from pre fluxing the pcb's , various ammendements to the oven profile and various pastes. Finally after a lot of help from multicore we settled on a paste by the code of cr39. A no clean flux wit

Thanks for the reply. I actually heard back from Kester who say they dont test with other fluxes (obviously) but that there shouldnt be any issues. Of course they recommended their wave flux to replace our Multicore and can confidently then say there

What is the solder finish of the board?. If this is gold, maybe you should check the reflow profile and max temperature which can easely kill your gold coating so problems with bonding. Also we are using Prozone Multicore with ultrasonic to clean

Hi all, I have an inconsistent situation. Lately, we seem to have excessive dross buildup in the solder pot which inturn causes the pot to overflow. Has anyone had a similar experience? Here are the details: age of machine= 9 years, flux used= Kester

IPA is a fire hazard. Be sure your fire extinguishers are charged and your evacuation plan is current, when using IPA in the vacinity of a wave solder machine. Have you tried DI water? Solutions used in wave finger cleaners include: * Techspray SMT
