Hi you there, Do you have any experience upon the shelf life of PCBA which passed 100 cycles of liquid to liquid thermal stress test, 125 to -35 centigrade for 15 minutes and 5 seconds of transfer time from 125 to -35 centigarde. Will apprecia

You may struggle finding the information that you seek, because there is so much variability in the design and fabrication of boards. * What is the purpose of such a test? * What product type sees such an use environment? Consider using the guidelin

Dear All, I have OSP finsh pcb on my production, the pcb thickness is 1.5mm and the product is one sideded pcba. After reflow process, Is there any specific time frame defined for smt completed OSP finish pcba before going for wave soldering proce

Suppliers have improved the utility and quality of OSP [organic solderability preservative] solderable surface protection over the years. Be cautious reading too much into older SMTnet [and web in general] conversations about handling OSP. When prop

Hi there Siemens Valor Proceed Preparation is a alternative that I would say ticks your boxes as is more focused on PCBA NPI process , from Cad-Cam Data clean up SMT programming, Stencil Design, Assembly Panel Design, Test Engineering, DFA analysis

Hello Stephen, thanks for the advice. We are producing LED TVs & we have a facility for SMT and manual insertion. We are also thinking of changing the board finish from OSP (due to its shorter shelf life) to ENIG/Immersion Tin.

I am looking to learn of possible causes and solutions for the following problem. A potential customer is demanding that I use a saponifier in the aqueous wash, he has lab test results of former CM's products that leads him to believe it is necessar

To you all for comment and summary, The following things I like without endorsing (PCB/PCBA stuff - outside the great women in my life [many] and without [mostly]): 1) A good set of design rules 2) A good set of design rules meeting producibility r

Hi, This Not so easy as one wuold think. Has the thermal pad of yours vias? How many? What's the via's dia? What is the pcb thickness? If the the pcb has a "ground layer" connected (vias) to the pcb thermal pad, it could sometimes be a little bit tri
