Abstract
The utility model relates to pcb board, relates to its plate face structure especially.Object is to provide a kind of easy to operate, pcb board that Manual Visual Inspection is easy to the uropore with detection aperture mistake.Have a pcb board for the uropore of detection aperture mistake, have this plate, above-mentioned panel edges is provided with uropore, and above-mentioned uropore linearly equidistantly arranges by size.This novel benefit is designed by equidistant uropore, and wrong aperture can open-and-shutly be found out, thus improve checkability.
Description
Technical field
The utility model relates to pcb board, relates to its plate face structure especially.
Background technology
Pcb board is exactly printed circuit board (PCB), almost appears in the middle of each electronic equipment.And electronic component is just set on the pcb board of different sizes.Along with electronic equipment becomes increasingly complex, the part of needs gets more and more, the circuit on pcb board and part also more and more intensive.This plate is by insulated heat and unbending material forms substrate, the tiny line material can seen on surface is Copper Foil, originally Copper Foil covers on whole plank, and part is disposed by etching in the fabrication process, and the part stayed just becomes webbed tiny circuit.These circuits are referred to as wire or claim wiring, and the circuit being used to provide part on pcb board connects.
Electronic component is just set on the pcb board of different sizes.Because each component's feet is not of uniform size, PCB needs the through hole getting out various different-diameter, conveniently confirm that whether aperture is correct, general PCB company is when holing production, the edges of boards often last processing stand of drill point being placed on working plate can be designed in boring formula, be referred to as uropore (lasthole).General uropore is arranged in a linear shape, and after boring terminates, inspector uses divider to measure each uropore, and confirm that whether diameter correct, this operation is more loaded down with trivial details, therefore under desk checking condition, find a kind of easy, intuitively check system seem very important.
Utility model content
The purpose of this utility model is to provide a kind of easy to operate, pcb board that Manual Visual Inspection is easy to the uropore with detection aperture mistake.
The technical scheme realizing the utility model object is as follows: a kind of pcb board with the uropore of detection aperture mistake, has this plate, and above-mentioned panel edges is provided with uropore, and above-mentioned uropore linearly equidistantly arranges by size.Above-mentioned uropore spacing d is 0.1mm.This novel benefit is designed by equidistant uropore, wrong aperture open-and-shutly can be found out, facilitate inspector to detect defective products fast, and do not need the aperture of each uropore measuring every block plate, thus improve checkability.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
Embodiment
See Fig. 1, this novel pcb board with the uropore of detection aperture mistake, have this plate 100, above-mentioned panel edges is provided with equidistant uropore 1.When detect aperture makes design, the pitch of holes of each uropore is designed to certain value, particular hole spacing adjusts according to drilling machine precision, general drilling machine precision is between 0.05-0.075mm, drill point every 0.05mm be a grade, then uropore spacing can be designed to 0.1mm, in case the uropore that the skew in boring normal range (NR) causes intersects cause erroneous judgement.
As long as whether inspector's visual uropore when checking intersects or spacing obviously widens, can be confirmed whether to there is wrong aperture, re-use divider to go to confirm concrete diameter, and do not need to use divider to confirm the uropore of every block plank, greatly reduce Check-Out Time, improve checkability, and when investigation reviewed by bad plate, also seem more convenient, be easy to investigate out bad plate.
Obviously, above-mentioned embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to the utility model execution mode.For those of ordinary skill in the field, can also be easy to make other pro forma change on the basis of the above description or substitute, and these change or substitute and also will be included within protection range that the utility model determines.
Claims (2)
1. there is a pcb board for the uropore of detection aperture mistake, there is this plate (100), it is characterized in that: above-mentioned panel edges is provided with uropore (1), and above-mentioned uropore linearly equidistantly arranges by size.
2. the pcb board with the uropore of detection aperture mistake according to claim 1, is characterized in that: above-mentioned uropore spacing d is 0.1mm.
