Hi there, Is anyone familiar with a method to extract and analyse performance management data from iPulse machines? I am aware that the iMS software contains an option under user parameters to output performance records, but the format in which it o

Hi All, Would just like to course through this concern on a product that we are contracted to assemble. It is mainly used for an automatic hand sanitizer dispensing product. By design there is a restrictive value of current that it needs to dissipat

first check fuses in Y1 case. thats where EuroSYS cards are, and message you get tells you that cards can not communicate with main processing board in Y3 case via RS485. after that check cables and connectors. there are 4 EuroSYS cards in Y1 case, t

I guess these boards only used Fly test. Flying needle test is one of the methods to check the electrical function of PCB (short circuit test). The flight test machine is a system for testing PCB in a manufacturing environment. Instead of using the

Hi Rob, Thanks for your fast response. In fact, after a better look to driver boards, it has leaking SMD Electrolityc caps. Unfortunately after replacing them in 3 units, one of them gives 90% of times, ALARM4 led ON. Looks like a comunication pro

Here's a link to an article regarding foam mitigation techniques. It my be helpful. There are many causes of foam. Water alone does not foam. Flux, solubilized in to the water can produce foam. Defluxing additives contain defaming agents which should

Hello Hai, The first step is to determine where in the process the bubbles are being generated - either during coating or during curing. You can easily check this by letting a few boards air dry (no oven) and comparing them to the oven-cured ones. I

Has anyone else been experiencing this lately? We have had a rash of boards that come in properly vacuum sealed. We store them in the hot room until we are ready to build, and we get bubbles under the solder mask. We've had 4 different jobs, all di

Principle A layer of photosensitive material (photosensitive oil or dry film) is applied to the copper foil on the board surface, and PCB manufacturer should be use the position is exposed by black film, This applies to most PCB factories, especially
