Hi, I have some questions about material used in PCB for RoHS compliancy. It seems to be fuzzy between may manufacturer. Here are my questions: 1) What is the recommended material for lead-free assembly? 2) What's the difference between FR4 High Tg

Hi all, we are manufacturing smt components and some weeks ago our customers are facing many problems related to weeting and solderability. I know it is due to the Lead free processes, but anyway, we are quite confuse. In case it was possible, what c

ECD's OvenRIDER is the only instrument I know that can measure thermal transfer efficiency of a an oven. I suppose it would work for environmental chambers too. This instrument has thermocouples to measure ambient temp of oven zones and well as hi-ma

Hello John, There are some coatings for aluminum to eliminate solder drag out. The do not work with all fluxes it is called hardcoat anodized it is black or geen in color. Unless you have faily high volumn the hard coat cost can be as high as titan

Stepped stencils are usually the result of some dumb customer's requirement. 2 examples I can give: 1.) Customer demanded 50% wick-up the termination of a MELF component. No way you can get that from reflow. Played around with a drastic "step up

I can't tell you what's good, but I can tell you what's bad. We use JD Edwards. To give you an idea of how well it is suited to the electronics environment, most of the help screens, should you be able to find them, use recipes for bread and food

Hi, We have recently purchased a Quad IVC 115 pick and place machine but are finding it difficult to place SOT23 and similar components. The Visual alignment system rejects the components. We have manually measured and also got the system to measure

We have a customer transitioning slowly to lead free due to necessity rather than a need to comply i.e. some of their BGAs can only be purchased Pb free only. So for this we would want to produce them a leadfree soldered PCB (not necessarly RoHS comp

I unfortunately cannot post any photos, the unit in question is classified. And, as far as my comment that the BGA profile can be manipulated, if an engineer is also working the process with one of the operators, they can override the profile at any
