So, why can't you clean misprints on Entek boards? Entek: Cheap, flat, OK shelf life, not without process and fabrication issues. Your Entek organic solderability protection is probably Entek Plus [CU106A] made by Ethone OMI. Consider getting a co

PWB shelf life: HASL---3mth ENTEK-- 2mth Before using expired PWB, it is suggested to go thru HASL or ENTEK angain. Ask your VDR to serve this. Re immersion Au, mostly when the thickness under 3u"(micro pores present), the surface gold will serve a

I've had some field reliability and Accelerated Life Test (ALT) issues with BGAs on Entek coated Cu. > The best results so far are with Atotech coated Gold electroplate finish. > Solderability, for factory process, seems to be as described by Justin

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

You aren't going to post our stuff on your "Hey, I'm the wizard site", are you? Board fab, Pad coatings, OSP 1 OSPs: Imidazole (Via Systems) is good. Entek (Enthone) works, but requires strict thickness control in fab. 2 Enthone CU56 allows one t

Thanks Ken for your reply. Concerning OSP, there are a few negative points that I must considered for our application. I've read all the following points in an Entek document. Never test it. - If you have a miss print and you clean the PCB, the co

| Okay, here's a stupid question. What exactly is HASL and OSP? We are going to delve into this technology where I work and I want to utilize the wealth of knowledge here to make life easier. Specifically, what are the differences, the advantages, di

I've had good and bad experiences with OSP's. First of all, ask yourself, "Why use an OSP?" If you don't need it, don't use it. Solderability is dependent upon the number of thermal passes (the fewer, the better), the thickness of the coating, the
