8.2.5.5 Flat Ribbon, L, and Gull Wing Leads, Maximum Heel Fillet Height (E). For class 3 the heel fillet cannot touch the body of a plastic component, except for SOICs and SOTs. Why is my question? What type of failure will be the result of solder

I have experienced the exact same problem with excess solder touching the plastic component body. The solution in my case was simply to replace the stencil. I was using a reusable stencil frame that had been worn out. I replaced the stencil with a so

We use same methods of PCB attachment to carrier as Rob lists. To be more specific on pocket size, we machine our durostone carriers so there is 0.010 inch gap around perimeter of board. This might seem like a lot but (from my experience) you will

Hello, My Friend from USA wants to set up new factory for SMT production (expansion line). Currently, he has production lines in the USA (10 lines with testing). Initially, he will set up 3 lines to produce power supply like AVR and UPS. He doesn't

Thick, hard conformal coatings of acrylic, urethane and epoxy have a well documented history of causing solder joint cracks and breaking glass/ceramic and other brittle components. Dissimilar expansion and fairly high surface bond strengths of the ma

Without seeing a picture, my first instinct would be first and foremost some fixturing that provides full support for your print process. After that, since you are citing bow and twist, consider that the fixturing might as well travel through the ov

Thanks a lot , my application is cryogenic in nature. I am trying to make a Sub-Angstrom resolution Thermal expansion sensor, whose components have been machined out of OHFC copper, and i needed to solder a manganin wire to one of the capcitor plates

Hi Ringel, There's lots that fit that range, but a great deal depends on the support in your location, budget, number of changeovers, number of component types (feeder positions required) how many shifts you plan on running, future expansion plans e

You can use one but over spec it. It will be a non-linear problem to figure out how much each exhaust port exhausts. Also have lots of shut off valves to shut off exhaust ports that you are not using. We have some holes in the walls in the back of th
