High Frequency PCB | RO4003C, RO4350B, Ro3003, Ro3010, and RT5880 etc with frequency typically in the range from 500MHz to 2GHz, products are applied to power devider,radar,satellite system, mobile phone reception base station and so on. |
Carbon Ink PCB | As carbon ink pcb has very good resistance value that will help supply good conductivity. Carbon ink pcb is widely used in automotive filed, medical electronics,communication equipment and so on. |
| Special Material PCB | Rogers4350,Rogers4003,Arlon 25FR,25N for Ceramic PCB powder filling, Rogers series, Taconic series,Arlon series,Nelco series ect for PTFE high frequency material. |
| Thick Copper PCB | Ensure that there is enough thick copper plating in the hole to ensure that the resistance is within the range of the process requirements. 70% of the circuit board to complete the use of 35um of copper foil thickness, some will use 70um , 105um ,140um copper thickness and so on. |
Our Main Products
pcb assembly service Certifications
PCB Factory and Machine
Dalian BLD Eletronic Co., Ltd was established in 2002. We mainly offer high-precision single-side, double-side, multi-layer printed circuit boards, LED aluminium printed circuit board, customers components procurement and PCB assembly (SMT) business.
Now the production capacity of our factory has reached 600,000 square meters annually. And our products apply far and wide in many fields such as communication, computer, mobile phone, eletronic equipment and electrical appliance.
We established an assembly line in 2010, all the assembly machines were purchased from Pnansonic, which can assemble the components of 0201. The production capacity of the PCBA are 2,000,000 points per day.
We have two large plate warehouses, our plates contain different thickness, different varieties, different copper thickness, which is able to meet different requiremets of our customers
Drill is very important, so we have a perfect drill management area, and a machine 24 hours polished to ensure the quality of the drill bit.
We use the VPC (Vertical Continuous Plating) to ensure that the plated surface is smooth and uniform.
For multi-layer sheet, we use AOI equipment for inner inspection to ensure the inner quality.
