... Since 2004 we deliver our customers with RoHS compliant PCBs in different surface finishes – including also lead free Hot-Air-Levelling, Immersion Tin, Immersion Silver | PRINTED CIRCUIT BOARDS INDUSTRY | and Immersion Gold. More | UL-APPROVAL | The letters UL stand for Underwriters Laboratories Inc., this organization is an independent, not-for-profit product-safety testing and certification | PRINTED CIRCUIT BOARDS INDUSTRY | organization. | IN THE BEGINNINGS OF UL | more than 100 years ago stood questions in the range of fire-protection-mechanisms in the foreground. Today all | PRINTED CIRCUIT BOARDS INDUSTRY | possible products, materials, constructions and systems are tested and evaluated regarding their electrical danger as well as their danger of accident and fire. And in | PRINTED CIRCUIT BOARDS INDUSTRY | addition there were examined alarm systems and the ability to discover, control and prevent fire. | UL DEVELOPS SAFETY | regulations, which are taken over | PRINTED CIRCUIT BOARDS INDUSTRY | frequently as ANSI standards. Underwriters Laboratories certify and register customers according to ISO 9000. More... | PRINTED CIRCUIT BOARDS | | RAPID MASS ...

... The storage time of PCB`s should be as short as possible. PCB`s should be taken out due to the „first-in, first out“ rule. The | PRINTED CIRCUIT BOARDS INDUSTRY | the polyethylene packages should be taken away just before the assembling. Remaining PCB`s should be repacked again. To avoid exposure to draught, the packages should | PRINTED CIRCUIT BOARDS INDUSTRY | be stored in boxes. A.4 3 ) Soldering tests PCB`s stored for over several months and being transported under questionable conditions, should be submitted again | PRINTED CIRCUIT BOARDS INDUSTRY | to a soldering test, being equivalent to your soldering process. A.5 4 ) Heat conditioning of the PCB`s In any case we suggest a drying | PRINTED CIRCUIT BOARDS INDUSTRY | process of the PCB`s in a stove to reduce the moisture in the PCB`s to an acceptable minimum. Following parameters can be recommended: A6) Drying | PRINTED CIRCUIT BOARDS INDUSTRY | time: Temperature C° 8 hours 120 10 hours 100 18 hours 80 Lower drying temperatures are also possible but need much more exposure time. We | PRINTED CIRCUIT BOARDS INDUSTRY | also suggest to put the PCB`s vertically in the stove by using a rack. Good results can be achieved if the assembling ...

Good results can be achieved if the assembling | PRINTED CIRCUIT BOARDS INDUSTRY | process of the PCBs is started immediatedly afterwards. The time after drying should not exceed 48 hours not to rise the risk of delamination again. | PRINTED CIRCUIT BOARDS INDUSTRY | Forming Microvias. (Demand for small holes is ramping, with CO2 lasers leading the way) Thanks largely to the proliferation of smaller, more complex electronics devices | PRINTED CIRCUIT BOARDS INDUSTRY | such as cell phones, personal digital assistants, and notebook computers, the PCB industry is experiencing an overwhelming rise in demand for high-density interconnect structures (HDIS). | PRINTED CIRCUIT BOARDS INDUSTRY | The demand for HDIS translates directly into a vigorous market for the ...
