COUNTER SINK VS COUNTERBORE

Sunday,Jan 06,2019

COUNTER SINK VS COUNTERBORECOUNTER SINK Countersinking is done by making a cone shaped hole which allows a flat head fastener to sit flush when installed. This prevents any snagging or damage from the top of the fastener, which can happen if it isn t flush to the surface. With wood if you don t countersink and force the screw into the surface it will not only look bad, but the stability of the wood will be compromised. The wood can crack and split from the screw being forced and the fibers become damaged and dented. Countersinking also allows you to have all your screws at the same consistent depth.

Resin plug application and process

Wednesday,Dec 26,2018

With the development of miniaturization of assembly components, the layout area and pattern design area of PCBs have also been continuously reduced, and PCB manufacturers are constantly updating the production process to conform to the development trend. The application of the resin plugging process has also become more and more extensive, and it has been used in HDI panels.

Immersion gold VS Plating gold

Wednesday,Dec 26,2018

There are several surface treatment for PCB board: bare board (no treatment on the surface), rosin board, OSP (Organic Solderability Preservatives), HASL (lead tin, lead-free tin), plating gold, immersion gold, etc , these are relatively conscious treatment Many people can t tell the difference between plating gold and immersion gold, thinking that it is the same thing, it is a big mistake The following is a brief introduction to the difference between plating gold and immersion gold

Chinese New Year 2019 - time to prepare for your PCB production!

Tuesday,Dec 25,2018

Chinese New Year 2019 - time to prepare! The public Chinese New Year holidays 2019 are February 4th through to February 10th. As this is a nationwide national holiday it affects all production, and we are preparing action plans to find different ways of working around disruptions. All our efforts are always focused on your production, and our Management team will be manned during the whole Chinese New Year. But despite all the precautions we are taking, it could be good to think ahead and plan for the Chinese New Year to avoid disruption in your production.

One article take you to know AL-based board

Friday,Dec 14,2018

The aluminum-based board is a unique metal-based copper-clad aluminum substrate with good thermal conductivity, electrical insulation properties and machinability. At present, ceramics, copper are generally high in heat conductivity, but most of the current market is aluminum substrates due to cost considerations. (1) Heat dissipation At present, many double-layer and multi-layer boards have high density, high power and difficult for heat dissipation. Conventional printed board substrates such as FR4 and CEM3 are poor conductors of heat, which are insulated between layers and heat is not emitted.

Why do you need Stiffeners on Flex PCB?

Tuesday,Dec 11,2018

Flex PCBs are thin, light weight and easy bending, this gives much difficulty in the process of component assembly Stiffenersare used to reinforce those areas where components will be assembled There are many different material can be used as stiffeners, like polyimide, kapton, FR-4, A

What are the biggest challenges in starting a hardware company?

Wednesday,Oct 17,2018

Hardware company is used too broadly Both Square and SpaceX arehardwarecompanies, but with very different challenges It’s like lumping together enterprise Saas, social apps, and AI all together as software companies So I’d think about subcategories and challenges facing each

Comparison of several PCB surface finish types

Monday,Aug 13,2018

Comparison of several PCB surface finish typesAs for the essential proceed in PCB production, the basic purpose of surface treatment is to ensure good solderability or electrical properties. Since copper in nature tends to exist in the form of oxides in the air, it is unlikely to re...
