| If passive componets are cheaper why aren't they more popular? Manufacturers like Murata and AVX claim availability and substantial cost savings but little interest seems to exist. Why? Your input is greatly appreciated. | It is my understanding

Has anyone had experience using Copper Passivate coated PWB's, our supplier calls them "flux coated" but as it's an Organic finish is it handled the same as Entek and where can I get details about it?. I have used Entek CU56 & Entek Plus coated PWB's

Hi, We are using well over half a million a month, so it's not as much as the bug guys, but we really need them from the manufacture direct. I think we have found some, and wow can you get a lot of passives on a 13 inch reel! Regards, Grant

Assemblies are stored on ESD rubber covered flat trays. The trays are stored on rolling carts with slots for the trays (Bliss cart). The damage usually occurs on the bottomside (passives only). This side is more susceptible to damage because the sm

Chances are this is not a component failure. First, these are passive components with passive testing on the ICT. He may have guarding issues, but more information is required as has been stated. Are all capacitors with the same P/N failing in dif

I'm not sure I'm offering an answer, more a question I have...Isn't there an issue with automated PnP machines whose feeder carriage moves? Have companies such as Fuji, Universal/Sanyo, Panasonic developed the capability to use bulk feeders? I woul

Current Acceptable HMP Soldering Methods: 1. Wave / Selective Solder: Some Brands require upgrades to heating elements and Pot materials 2. Laser: Works well with PTH and medium/large passive SMT. Damage to PCB masking can occur when try

We are converting from COB to SMT on a product line and want to optomize the PCB as far as Laminate, plating, passivation etc. This is a high temp application 150C. We are presently using BT Laminate but would like to get away from this. We are lo

Another concern is that some bulk feeders present resistors upside-down 50% of the time; I'm told that this can affect heat dissipation and cause other problems (e.g., hidden partmark). Note: this is not a problem with chip capacitors because they'r
