Single Sided Universal PCB Prototype Board Bakelite Matrix Plate 5*7 7*9 - 12*18
Product Information:
- Name: Single-sided bakelite universal circuit board
- Substrate material: bakelite material (the CNC board is fire-resistant, and the stamping is ordinary)
- External dimensions: 5*7CM, 7*9CM, 9*15CM (glass fiber board is recommended for large size)
- Aperture: 1.1M (error 5%)
- Hole spacing: 2.54MM (100MIL)
- Stamping plate thickness: 5*7 and 7*9 are 1.2MM thick, 9*15 is 1.5MM thick
- Thickness of CNC plate: 5*7, 7*9, 9*15 are all 1.5MM thick
- The difference between stamping and numerical control: stamping is a mold, and all the holes and shapes are punched down. The advantage is that the speed is fast and the cost is low. The disadvantage is that the board is bent. Numerical control is to use punching machine to punch holes, gong machine to shape the size, the board is not deformed, the hole and appearance are better than punching, the hole is very centered, welding is simple, the selected plate is also changed to red letter fireproof material and 1.5 thick plate.
- Little common sense: The difference between glass fiber and bakelite is that bakelite is cheaper, its natural hardness is not as strong as glass fiber, and it is easy to bend. If it is bent, it is normal (99% of bakelite is bent), because the hole is punched, you can just break it by hand. If you have higher requirements, please buy glass fiber material. It is easier to solder if the pads have tin-sprayed (white pads).
- Note: If the solder pads fall off during soldering, please find out the reason for yourself, that is, the soldering time is too long or you touch it when using a tin absorber. Now the copper sheet is very firm, and those skilled in soldering want to It's hard to get rid of the pads.
