We are in the process of deciding whether to change a PCB product from a single board to a 3 up panel array. Could you please advise on the most effective removal design, either scoring or snap off, taking into account that material utilisation is i

We are a small firm currently examining a new system for our manufacturing operations. We do small volume, batch flow as an OEM and under contract. The company also performs PWB layout and engineering services. Ideally the system should be able to do

Does anyone have a tried-and-true method to account for machine losses of SMT parts? I remember reading an article once that stated that 5% - 10% of components of certain sizes are known to be lost during placement, and I know some CM's overplan by 5

We use DBA. dbasoftware.com They are supposed to come out with a new version in the next few weeks. Its cheap for something with integrated accounting and its decent but its still stuck in "windows sort of but works like dos". Hope the re-write is be

Ken, We're talking pennies. Even though the cost of a reel would be cheaper than trying to account for lost components I have to come close in figuring this attrition amount. Reason being is to try and prevent unplanned shortages. I am in constant

There is no substitution for proper calibration especally with ever decreasing size of parts. ISO certified companies and coustomer base often require calibration by qualified personel useing approved tools. Verification also in many cases be require

You should try looking into the Technical Devices Nu/Era. They offer the best warranty on their lead free solder pots. They use something called Titanium Nitride which has been tested to outlast Melanite. The dross produced on the TDC machines i

It depends. Let's focus. The basic versions of COB are: * Semiconductor die that you place on a glued board surface, wire bond, and then encapsulate. [The crazy uncle of the COB process, accounting for 90% of the placements.] * Semiconduct die tha

We sometimes use a peelable mask the the PCB manufacturer (board house) adds as part of their process. It may seem an expensive option but avoids: Raising P/o's for tape/peelable mask as consumables booking & inspection Booking out to the shop floo
